I need a clean, well-documented COMSOL model that captures the fully coupled electro-mechanical response of a piezoelectric polymer structure. The goal is straightforward: simulate and analyse how the chosen polymer behaves when mechanical stress and electrical fields interact, then extract the key performance metrics (voltages, stresses, strains, charge density, etc.) across the domain. The work starts with choosing or inputting the correct piezoelectric material constants, building or importing the geometry, and applying boundary conditions that reflect a realistic operating scenario. From there, the study should solve the coupled governing equations, followed by post-processing that isolates the most insightful plots and numerical results—field distributions, mode shapes, impedan...

roject Description I am currently working on a Master’s thesis project focused on the aerodynamic performance of axial fans. The goal is to evaluate airflow performance (CFM) for multiple fan geometries using Autodesk CFD. I already have several parametric fan designs created in CAD. What I need is help configuring one correct and reusable CFD simulation setup that I can later replicate for many fan designs. The freelancer is not expected to run many simulations, but rather to build a robust simulation template that I can reuse by simply replacing the fan geometry. Project Objective The main objective of the simulation is to: Evaluate and compare airflow performance (CFM) of axial fan designs. The CFD setup should allow consistent comparison between multiple fan geometries. S...

I need a production-ready CAD design for an electric battery lift mechanism used inside a compact consumer-electronics device. The lift must rise vertically and then rotate to present the battery for easy removal, all within a tight envelope. Along with the 3D model I also require mechanical analysis to validate durability, stress limits, and smooth motion. Key points you should know: • Motion profile: first a controlled vertical lift, then a 90-degree rotation (or equivalent) in one continuous sequence. • Actuation: electric only—no hydraulics or pneumatics. • Form factor: sized for handheld or desktop electronics, so space, weight, and noise are critical. • Materials and fasteners should favour mass-production methods such as injection-moulded plastics ...

I want to reproduce the finite-element strategy presented in the attached thesis and then push it further. Using ABAQUS, you will build a detailed FDM part model, calibrate it, and run simulations to predict three key responses: tensile strength, flexural strength, and impact resistance. The baseline geometry, material data and boundary conditions follow the thesis exactly; where we go beyond is in the process parameters. I am focused on a 45°/-45° filament orientation and a stack of multiple layers in which each layer can vary its orientation. Capturing how those two manufacturing choices change the mechanical response is the primary research question. Deliverables • ABAQUS *.cae and *.inp files for every configuration tested • A concise technical memo summarising as...

I’m putting together a short-run, high-impact training series for a group of advanced Power BI users who already build reports daily and are hungry for deeper mastery. The focus is squarely on data modeling strategies and sophisticated DAX techniques that move beyond calculated columns and measures into row-level security, dynamic relationships, optimization, and real-world performance tuning. The assignment is time-critical: I’d like to roll out the first session as soon as we lock in the schedule, so please be comfortable jumping in immediately. Sessions can be live online, but recordings and reusable reference material (PBIX examples, slide deck, and answer keys to exercises) must follow each class. To keep expectations crystal clear, I’ll sign off once I can: &bul...

I’m working on a refrigeration system and need a mechanical engineer with a strong thermodynamics background to dive deep into its heat-transfer behaviour. The goal is to quantify where energy is being lost, identify bottlenecks in the evaporator-condenser loop, and recommend practical ways to push overall COP upward. You will have to model the refrigerant flow, run the necessary heat-balance calculations, and translate the numbers into clear design or operating tweaks that could be implemented in the real plant. I’m comfortable if you prefer CFD tools such as ANSYS Fluent or SolidWorks Flow Simulation, or more analytical environments like MATLAB, EES, or even REFPROP—use whatever lets you capture conduction, convection and phase-change effects accurately. I’d lik...

I am looking for an experienced Abaqus FEM engineer to help create and verify a 3D finite element model of a helical pile embedded in sand. The goal of the model is to simulate pre-compression displacement followed by uplift displacement on helical pile to evaluate the effect of pre-compression displacement on uplift capacity. This task is only to build a working Abaqus model and verify that the pile–soil interaction is functioning correctly. The freelancer should verify that: Contact between pile and soil is active, The pile mobilizes resistance during uplift, The model runs without convergence issues. Output Requirements, The model should produce: Reaction force vs displacement curve for uplift, Contact pressure between pile and soil, stress contours, Uplift resistance develop...

Title: COMSOL Induction Heating Model – Debugging and Result Verification Description: I am working on a COMSOL model related to induction heating and need help checking the results and debugging the simulation. The model includes a copper coil, an aluminum cover, and steel pins. The goal is to analyze whether adding the steel pins significantly affects the magnetic field distribution and the heating behavior of the workpiece. There are two tasks: Task 1 – Result verification Two of the COMSOL models can run successfully, but one model produces an unrealistic result. After adding the steel pins, the temperature difference at the same time step is about 200°C, which seems too large. I would like help checking whether this difference is physically reasonable or caused by...

I have a welded steel-plate assembly that must stay as light as possible while remaining very stiff. Your task is to build a finite element model of this structure, focus on accurate deformation prediction under the specified service loads, and then iterate the design so the stiffness-to-mass ratio is maximised. You are free to choose the solver you know best—ANSYS, ABAQUS, SolidWorks Simulation, or any equivalent package—provided it can capture weld behaviour, material non-linearity if needed, and give me exportable plots and data. I will need a clear PDF report that walks through the modelling assumptions, boundary conditions, mesh convergence checks, deformation results, and the material/geometry changes you introduced to achieve the weight saving. Native solver files can b...

I’d like you to carry out a complete structural study for a single reinforced beam and show, in one concise package, how it performs under the specified service loads. The goal is to know two things with confidence: • the beam’s ultimate load-carrying capacity • the maximum deflection at mid-span and how it compares with code-permitted limits I will supply span length, cross-section geometry, load combinations and any code I must comply with once we start. If an FEA package such as SAP2000, ANSYS, STAAD, or Robot will speed things up, feel free to use it—just attach the native model alongside clear hand or spreadsheet calculations so I can verify the results independently. Whether the beam ends up being steel, concrete or a composite section depends on t...

I have a component that sees time-varying loads and I need its structural response captured through a full transient dynamic study written entirely in Ansys APDL commands. The geometry is already defined in a neutral CAD file; what I’m missing is a robust APDL input deck that sets up material data, meshing, boundary conditions, the load-time history, solution controls and post-processing so I can replay or tweak it on my side without Workbench. Because this is a structural, dynamic, transient analysis, accuracy in time-step selection, damping definition and result extraction (stress, displacement, reaction forces) is critical. Please use standard APDL best practices—element type justification, mass proportional damping where needed, and output requests that minimise file size ...

I need a complete structural evaluation carried out in ANSYS Workbench for a mechanical component that is already modeled. The task is strictly structural—no thermal or fluid-flow coupling—so please focus on static strength, deformation, and, if you judge it helpful, a brief modal check for natural frequencies. This is a single part, not a building, bridge, or aerospace assembly. You will receive: • the clean STEP file of the component • loading diagrams with magnitudes, directions, and boundary conditions Your job: • import and clean the geometry, create a high-quality mesh, and document your mesh-independence check • apply the supplied loads and constraints, then solve for von Mises stress, principal stresses, displacements, and safety factor ...

I am modelling a single-segment continuum robot whose backbone is manufactured in polyurethane and ABS. Your task is to set up and run parametric finite-element studies in ANSYS so we can see how the structure curves when one tendon is pulled with forces in the low 1 – 10 N range. For each geometric variant of the backbone I will supply (length, diameter, tendon-channel offset, bakbone type etc.), I need two clear results: • the exact tendon force applied, and • the resulting bend curvature radius of the backbone. Once all variants are simulated, please compare the force-radius trends and point out which configuration gives the most favorable bending performance so I can move forward with an optimal design. Deliverables must include the editable ANSYS project files, any ...

I am seeking an experienced mechanical or FEA engineer to perform a static structural finite element analysis (FEA) on a plastic lid component made from Polycarbonate (PC-110). The goal of the analysis is to estimate the force required to cause yielding or failure when a load is applied at the center of the lid panel. A STEP file of the part and a detailed instruction PDF are attached here. The simulation should apply a load perpendicular to the lid surface over a 1-inch diameter circular area at the center, while the perimeter of the lid is constrained as shown in the attached instructions. The analysis should gradually increase the load until material yield occurs (Von Mises stress ≥ 9,000 psi). Deliverables should include a short simulation report (PDF), stress plots, deformation plo...

I’m running a steady-state, two–phase condensation model for a single steam-carrying tube placed inside a rectangular duct through which the cooling medium flows. The goal is to quantify heat-transfer efficiency along the tube wall and map local condensation behaviour. All pre- and post-processing must be done in ANSYS Fluent – that is the environment my wider workflow depends on. I already have basic geometry and material data; what’s missing is a robust setup that captures phase change, solves for the temperature field on both sides of the tube, and outputs wall heat-flux, overall U-value, and condensate distribution with mesh-independent accuracy. Key points • Physics: two-phase (steam → liquid) condensation, steady-state, turbulent flow inside and ...

I have built several tractor-mounted boom extensions and now I want solid, engineer-backed numbers on exactly how much weight each point along the boom can safely handle. The boom is welded from a 3/8" side-steer plate and a 2-1/2" × 2-1/2" × 3/16" square tube. From the plate it runs straight for 10 ft, then kicks up at a 30° angle and continues another 2 ft, giving a total length of 11 ft 10 in. Its primary job is lifting pole-barn trusses, so the working load will sit in the 500–1,000 lb range. I don’t have to satisfy OSHA, ISO, or any other formal standard, but I do want a clear, defensible safety factor. What I need from you is a straightforward structural analysis—hand calculations, FEA, or a mix—that tells me: • Ma...
