Hi, Have you tried to run this simulation as "Single FDTD", instead of "Multiport"? You can convert from one type to the other by right-clicking on the simulation and choosing "Clone As" -> "Single FDTD".
I am not sure Multiport simulations have support for waveguide sources (and you have only one such source, so Single FDTD should anyway be what you need).

Next to the "Statistics"-button you can see a "Viewers"-button, which has a wide variety of options on how to visualize your data. It includes slice viewers where you can see the SAR-distribution of an arbitrary plane, a histogram plot option, and much more.

Dear Sim4Life developers,
I have came across the same problem and cannot update materials database due to the Russian words within a pathway.
Is it possible to solve this problem by directing Sim4Life to search for materials in another pathway?

Thank you a lot in advance,
Valeriia

Have you found an answer to your question already? If not, I would encourage you to read the corresponding sections in Sim4Life's user manual:
2.8.2 Thermal Simulation Settings
2.5.1.1.2 Numerical Stability (this is in the FDTD section, but the same criteria apply in the thermal solver)

If there is a message such as "Job Finished", this probably means that the job is not really "stuck" at 0% but that it simply failed, for some reason. You might get additional information by looking at the Console (View -> Console) or by looking at the log file from the solver itself (this is a file ending with _Input.log in the Results folder of the project). The latter is also visible from within Sim4Life using the Task Manager (click at the bottom right of Sim4Life to open it).

That solved the problem, thank you very much!

Right. Thank you very much for your explanation and comments.

Your approach is the correct one.
There are a few caveats that could explain the discrepancies in the results (one should, of course, obtain the same current flux between anode and cathode regardless of the method used):

the surface used to compute the flux should intersect with all field lines between anode and cathode, once, and only once. An example might be a plane that cuts through the head, with one electrode on each side. Another possibility is to create a box that encloses one electrode. In your example, with the sponge, I think you might have current entering from one side and leaving through the other and would actually have expected a total flux of zero. the surface needs to be correctly discretized. For that, try to reduce the Minimum Edge Length property of the surface in the Explorer tree (after drag & drop), then Refresh Viewers, until the Total Flux value stops changing I am not sure what happens if the surface is also a boundary condition for the J field (as in the case of your electrode). Maybe there are some discretization issues there. In all cases, it often helps to visualize the flux of J on your chosen surface, by using the Surface Viewer

I hope this helps

For FDTD simulation, you will need to excite the plates by joining them with a wire (use the Sketch -> Lines tool), as if you were building a circuit. Leave a small interval open somewhere so that you can insert an edge source.

Hi Saya, "parameters" are by definitions input by the user. Their values, as well as their standard deviation or any other statistics, can therefore not be "found" by the program itself.
Maybe it would be clearer if you could provide an example.
best regards

@Sylvain Thank you. I will try your suggestions.

Thanks for your help.
