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 ...

Project Description: I am looking for a COMSOL expert (chemical engineer / physicist) to simulate evaporation of liquid inside a vertical capillary tube using COMSOL Multiphysics (latest version preferred). Model Requirements: 2D transient model Geometry: Rectangle (0.025 mm width × 0.1 mm height) Vertical capillary tube Initially fully filled with water Room temperature conditions Evaporation driven by mass transfer (NOT temperature gradient) Outlet atmospheric humidity ≈ 50% Contact angle must form naturally (not fixed manually) Physics Expectations: Proper two-phase flow modeling (Level Set or Phase Field preferred) Surface tension effects included Transient moving interface (meniscus evolution) Realistic mass transfer modeling for evaporation Simplified or quasi-static ap...

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...

I want finite element analysis (FEA) of the Trinity miniplate, a medical device used in maxillofacial trauma fixation. Here is a prioritized list of the most important parameters to check in the FEA analysis of the VBH Trinity Mini. Plate: ## Most Important FEA Parameters—VBH Trinity Mini Plate ## Tier 1—Critical (Must Check) These are the non-negotiable parameters in every mandibular miniplate FEA. In all FEA models, maximum stress consistently remains on the miniplate itself. 1. **Von Mises Stress on the Plate**—Peak stress value (MPa) on the plate body, arm junctions, and screw hole perimeters; must stay below titanium yield strength (~880 MPa) 2. **Von Mises Stress on Cortical Bone**—Peak bone stress at the plate edges and screw purchase zones must stay be...

I need an experienced CAE specialist to help me finish my final-year mechanical engineering project: a fully detailed finite-element model of a small-caliber projectile striking a multilayer bullet-resistant vest. I have already defined the basic geometry and material stack-up in HyperMesh, and the plan is to solve everything with the explicit OpenRadioss solver. What I still require is expert guidance—and hands-on modelling work—so that the simulation reliably predicts: • penetration depth and overall armor performance, • the complete stress and strain fields inside the ceramic and composite layers (stress distribution, strain distribution), • projectile behaviour such as velocity reduction, deformation, and residual velocity, • correct energy accou...

I need to run a series of on-site load tests on several fixed posts installed in a confined area. Space restrictions mean the whole setup must rely on a compact, portable hydraulic arrangement rather than large jack systems or heavy rigs. The main goal is to confirm and fine-tune the posts’ performance under their design loads—this is strictly about performance optimization, not a one-time safety check. All procedures, calculations, and reporting have to align with the relevant international building standards, so any methodology you propose should reference the specific clauses you intend to follow. I will supply drawings, design loads, and access details once we start; you will handle everything from test plan to final report. Deliverables • A concise test plan showi...

I need a full electromagnetic design for a dielectric lens – or a compact horn‑lens combination – that concentrates microwave energy at 2.45 GHz from an existing 1 kW source in a controlled lab/industrial setting. The goal is to maximise the energy delivered to a small focal spot (target ≈ 2–3 cm at a defined distance), so the work must revolve around: Directivity Gain High power‑density focusing at the target spot Please model, optimise and document the antenna‑lens using a recognised 3‑D EM solver such as CST Studio Suite, HFSS, FEKO or similar. I will rely on your simulations to validate return loss, beam pattern, peak gain and the size of the focal region before we commit to fabrication. Deliverables Native simulation project files and exported 3‑D geometr...

Here is what I need from you: • Live or recorded sessions that walk me through project setup, mesh generation, material assignment, heat-source definition, and result interpretation. Complete study of the software and make me good in it. • Worked examples for each process (arc, resistance, laser) . • Tips on choosing solver settings so runs finish in reasonable time without sacrificing accuracy. • A short checklist I can follow after the training to make sure every new model I build captures the right thermal outputs. I already know welding theory, so the focus should stay on Simufact’s interface, modelling strategy, and validation of the simulation against real-world weld data. Remote delivery is fine—screen-share, annotated PDFs, or short videos al...

I’m completing a university project that calls for a full engineering design of a two-flange ball valve suitable for crude-oil service. The assembly—including body, ball, seats, stem, seals, and fasteners—must be laid out in stainless steel and verified against API 6A. While references to API 6D or 608 can guide good practice, every dimension, tolerance, and material choice has to pass an API 6A compliance review. What I need from you is the complete digital design package created in a mainstream CAD environment (SolidWorks or Fusion360). The file should be able to make edits and easy to revise for future FEA or CFD checks. Deliverables • 3-D solid models of the full valve assembly and each component (.STEP + native CAD files) • Detailed 2-D fabrication dr...
