The Ansys Lumerical HEAT solver offers some pre-run diagnostic tools that you can use to perform diagnostics before running the simulation, which can reduce the chance of erroneous simulation.
Partitioned volume mode:
The partitioned volume mode can be used to make sure the structure and simulation objects are set as intended and everything is in the right place. This mode can generate a partitioned volume of the simulation region composed of different domains and surfaces to represent exactly what a solver can see during simulation.
Error check tool:
The check button available under the Simulation section of the HEAT tab opens the Error Checking and Diagnostics window, which contains information as well as any errors or warnings related to the setup of your simulation. This can be used to address any issues regarding the simulation setup before running it.
In this video lesson, you will learn how to run the simulation and visualize the results from the HEAT solver and monitor objects. Various attributes and settings of the visualizer are also discussed.
