I need a COMSOL Multiphysics model of a high-frequency transformer that couples the electromagnetic and thermal physics so I can focus on thermal stress impacts. The goal is to see exactly where mechanical strain develops inside the core, windings, and insulation as temperatures rise during high-frequency operation. You’ll start from the transformer’s geometric and material data (I’ll supply those) and build a 3-D electro-thermal study that includes frequency-dependent copper and core losses, convection or forced-air boundaries, and, ideally, a transient run that tracks hot-spot evolution. Once the temperature field is solved, the model should translate that field into the corresponding thermal-induced stresses so I can compare stress levels against material limits. Bec...

I have a set of completed Abaqus simulations and now need a sharp, data-driven interpretation of the results. The focus is purely on post-processing: extracting the stress and strain fields from the ODB files, turning them into clear visuals and metrics, and explaining what they mean for the structural stability of the frames I am studying. Here are the exact result areas that must be covered: • Maximum stress points • Stress distribution over time (load increments / steps) • Comparative analysis between different simulations • Displacement fields • Any additional indicators that speak to overall frame stability I expect plots (contours, XY curves) and a concise written discussion that pinpoints critical regions, quantifies safety margins, and compares ...

Important: "Please read the project specifications carefully before submitting an offer. Once you bid on the project, your quoted price is considered final, and no requests for a price increase will be accepted." If you have any questions before submitting an offer, please contact me! Project specifications • Analysis Focus: The analysis must focus exclusively on the global stability of the stacked racks (checking for overturning, sliding, or separation between levels). • Structural Verification: Component-level structural verification (stress/strain analysis of the rack members) is out of scope. • Rack Simplification: Since the rack is entirely welded, it can be simulated as a single, rigid steel body. You may simplify the 3D geometry if necessary to optimize ...

I have an electric-field simulation set up in Ansys Maxwell, yet the field distribution patterns I obtain look nothing like the physical behaviour I expect. Geometry, material assignments, excitations and solver settings all appear reasonable, but every sweep still produces the same unexpected plots. I’d like a fresh pair of expert eyes to: • Review my project file step-by-step – geometry, boundary conditions, excitations, mesh and solver setup. • Identify why the results diverge from theory and provide the specific parameter tweaks or modelling changes that will bring the field plots back in line. • Guide me explaining the root cause and documents the corrections so I can reproduce the fix on future designs. Remote session access to my workstation is...

I already have my geometry ready and I now need it set up, meshed, and solved entirely in either PrePoMax or Mecway—whichever you are most comfortable with. Once you receive the model, please build the analysis from start to finish: define the contacts, choose appropriate element types, apply realistic loads and boundary conditions, and run the solver until stable, converged results are obtained. I will share further details about the operating environment, objectives, and any material data once we start so you can tailor the setup accordingly. What matters to me is that the project file can be opened and rerun on my side without modification, and that I receive a concise report summarising assumptions, key plots, and numerical results. Deliverables: • Native PrePoMax or Mec...

I need help turning our data-centre concept into a fully functioning Bentley iTwin digital twin, with an emphasis on simulation and modelling. The goal is to capture the entire life-cycle—from chip placement right through to deployment and ongoing operations—and then run detailed environmental simulations on that virtual model. Here’s what I expect: • A clean iTwin setup that accurately mirrors our proposed data-centre layout, equipment stacks, power and cooling paths. • Environmental simulation scenarios that let us test heat distribution, airflow, energy consumption and failure contingencies before we build anything in the real world. • Clear, repeatable workflows so my internal team can update the model as designs evolve. • A concise report ...

I need a custom dunnage block engineered that can live permanently in coolant without swelling, cracking, or softening and still support up to 90,000 lb. The footprint has to stay close to 2 ft × 4 ft so it drops straight into our existing material-handling cradles. Material preference: molded or machined Polypropylene for the main body. I chose PP because we have long exposure to water-soluble and straight-oil coolants; HDPE swells a bit for us and PVC is too brittle. Internally, I want a hollow-section design to shave unnecessary weight and cost while keeping the outer walls thick enough to handle the compressive load. On the underside I need bonded or mechanically-locked strips of Nitrile rubber so the block will not skate around on steel skids or machine tables when a forklift ...

Preferred Freelancer Locations: We are specifically seeking engineering talent located in major manufacturing hubs, including the USA, UK, France, Italy, Spain, Poland, Germany, Russia, Japan, or South Korea. Expected turnaround for the first draft should preferably be within 4–6 days depending on the data shared. Multiple revision cycles should be included to finalise the design efficiently.

I’m building a new benchmark to measure how well frontier language models cope with genuine scientific workflow. Your role is to craft one self-contained, terminal-driven research task that feels exactly like real lab or data-science work—analysing raw data, running simulations, validating a hypothesis, comparing competing methods—rather than a polished textbook exercise. The task should force multi-step reasoning and code composition so thoroughly that today’s best models fail at least 80 % of the time, while an expert human (you) can still solve it reproducibly. What I need from you • A complete task package zipped together: – explaining the workflow, required inputs, expected outputs and the objective success criteria – A fully reprod...
