Comprehensive ANSYS Multi-Physics Simulations

I need a single engineer who can run an integrated set of ANSYS studies for the same copper busbar assembly, covering electrical, thermal, weld-zone, and fault/runaway behaviour.

Electrical domain First, solve the steady-state current flow. I want current distribution, voltage drop and total resistance mapped, then dive deeper into I²R power loss and the location/size of any high-resistance zones. The geometry, material properties and boundary conditions will come from my CAD model and test data; you will import them, set up the XXXX XXXX or HFSS environment as appropriate, and provide both the field plots and the raw result files for post-processing.

Thermal domain Using the losses calculated above, predict the transient and steady-state temperature distribution. I need maximum temperature values, hotspot coordinates, a temperature-rise-vs-time curve and commentary on overall heat-dissipation performance. Coupled electro-thermal analysis inside ANSYS Workbench is preferred so mesh and loads stay consistent.

Weld zone modelling During TIG welding of two segments, capture the moving heat source, generate the temperature profile, delineate the Heat-Affected Zone, estimate weld penetration depth and compute residual stresses. The goal is to correlate the simulated HAZ with micro-section images I will supply, and flag any stress concentrations that could compromise weld quality.

Thermal runaway / fault scenario Finally, drive the model into an over-current short-circuit event. Report peak temperature, time-to-failure, runaway propagation path and predicted busbar melting/fuse behaviour. Include the short-circuit current waveform used as load input.

Deliverables • ANSYS project files for each physics setup, fully solved • High-resolution plots (PNG + native ANSYS reports) for every metric listed above • A concise memo summarising methodology, key assumptions, mesh independence check and results interpretation

Acceptance criteria Results must converge within 5 % of the supplied benchmark measurements; mesh sensitivity documented; and every item in the deliverables list submitted in an organised folder structure.

If you have completed coupled electro-thermal or weld simulations in ANSYS before, please mention them when you send your proposal together with an expected turnaround time.
