I seem to encounter a new problem with the simulation of this project. The goal is to have a 3 electrode model that emits RF radiation into a tumor. While the 2 electrode model works fine, meaning that both electrodes have E-field and SAR values, the 3 electrode model doesn't and I can't seem to find the problem. I tried to set it up exactly like the 2 electrode one, but it doesn't work. I get either 1 electrode working or 2 depending on the setup. Could you please have a look and maybe find the problem in my model? First 2 pictures are of the 2 electrode model (working) and the last 2 of the 3 electrode model in which only the Electrode-Insulator pair is working and gives SAR values. I know that the settings aren't the same, but even if I set it up exactly the same way as the 2 electrode model, the same problem appears. ![image: 1558340209112-screenshot_4.png] [image: 1558340209075-screenshot_3.png] [image: 1558340209038-screenshot_2.png] [image: 1558340208992-screenshot_1.png]

@montanaro , Ohh that is maybe a better solution to the current problem, awesome:)

Okay awesome, I think this will do the trick :)

Yes, deleting the line you mentioned has solved the problem. Thank you again for your help Sylvain.

@Sylvain Thank you, I think that has solved my problem

Thanks, Why the dimension of the axis are different and so how to reshape the SAR with different dimension of axis vectors ?

Actually the temperature rise is very lower than what is measured in the lab and I'm wondering what is the reason. I extract the max temperature at a point using a line passing through the point (I find lines of the intersection of the 3 slices xy-xz-yz at max). But the value is much smaller than the value which a point sensor gives and also the max value which the color scale bar shows. What is the reason?

The 10 g PsSAR can not be calculated as well. The density of Gel in the simulation is 1000 kg/m^3, the length of a cube with 10 g should be about 20 mm. what the max step value should be based on the cube length? I did the simulation with the max step 0.1 mm and it seems it should be able to calculate 10 g PsSSAR. But it still can not calculate it and gives the error.

Thanks for your reply.

Yeay. It worked. Great. Thank you so much for your patience :)

Can't you do the same procedure directly for the E_tan along the baseline, instead of doing it for the random splines?

Hello Sylvain, Thanks for your reply.

Do you know which of the four steps is slowing down the pipeline? Because you could always choose to go for a more dedicated programming language rather than python to do part of the processing.

The Field_Combiner will allow you to sum two E fields, provided that they are at the same frequency. However, I think this combiner requires that the two fields are on the same grid. This means you may first have to use the Interpolator algorithm first (Select both fields, choose the Interpolator in the ribbon, and it will interpolate the first field on the grid of the second).
