EM FTDM simulation

[PG]

Hi,
I'm a student and I have Sim4Life Lite. I am a beginner. I have imported 6 meshes from Rhinoceros 3D in STL format. My solids represent a human neck with different layers and a tumor inside. I have reconstructed one dipole antenna. I am running the simulation, but it'll finish in 1200 hours. How can I reduce this?
The strange thing is that if I stop the simulation I get this message "Steady state detected at iteration 174139, remaining time steps are 959016", but the time is reduced to 14 hours.

Could someone please help me out?

Thanks!

Hi @PG

please have a look at the following posts:

Thank you; it's all clear. One more information: I have a solid that is more internal than others, and this one has a high and stable temperature. I want to do a thermal simulation using Pennes. As sources, do I have to set anything? Should I just set the temperature of the solid in the boundary conditions?

Joule heating sources from various processes (e.g., EM energy deposition by ohmic losses) can be considered as inhomogeneous heat sources in thermal simulations.
To create heat sources

1. Simulation Link: Sensor settings of an EM FDTD simulation in the same project can then be dragged and dropped into Source Settings folder.
2. Modulated Analysis/Cache: Data Origin Type can be defined as:
   (a) Cache File: select the path of a thermal source previously exported into a .cache file.
   (b) Analysis Output: select the energy density of interest directly from the Analysis.

You can look into the heated brain tutorial for a simplified example.
