@dstoupis We just figured out an issue with the Sweeper and Optimizer in Sim4Life light 5.2.1.1375. We have starting on working on a fix which should be available in the coming few weeks. If you urgently need to use the features, you have the option to use an older version of Sim4Life light, e.g., 4.4. If you do not have the installer anymore, please drop us a light at s4l-support@zmt.swiss.

Are you perhaps using Sim4Life using Remote Desktop or TeamViewer, or something similar? There are sometimes issues with the graphics drivers when using those software, preventing the Workbench to work correctly. If that's the case, there should be some warnings/errors in the Console when you start Sim4Life, mentioning issues with OpenGL.

Hi, I would advice you to look into the Tutorial examples related to 5G (in the FDTD or Optimization tutorial sections). They all include some analysis of beam patterns. The key ingredients are the "Far Field Sensor", the "Radiation Evaluator" and the "1D Filter"

Thank you. How can I display the big green arrow that shows the max direction. There was an option "Show Max Direction" (see screenshot above).

Dear supporter, It did actually speed the process up quite a bit. Thanks a bunch.

@Spuky you are looking for the "SAR Statistics" algorithm, in the Dosimetry tools. It is computed directly from the E-field and is different from using the "Statistics" algorithm on the "local SAR" field. [image: 1573025607511-b68d7134-8261-434e-8c4f-e58c36892e21-image-resized.png]

after the line sensor_extractor.Update() you can access the data using either: sensor_extractor["v"].Data.GetComponent(0) (if 1D data) sensor_extractor["v"].Data.Field(0) (if 3D data) these return the numpy array holding the raw data. Type dir(sensor_extractor["v"].Data) in the Console to get a list of available functions that can be useful for Data objects.

@Spuky Hi, the Workbench does not allow "dragging" input or output connections (yet). However, if you select an algorithm (which you can do in the Workbench), you can change its "Input Connection" in the "Properties" window: [image: 1568356305618-2019-09-13-08_30_15-_patch_mmwave.smash-sim4life.png]

Hi Sylvain, Thank you for your reply ! Indeed, it seems that one of my components was holding so much current at the end of the simulation. After I increased the number of periods, the results were more consistent. However, even before, the global convergence level was better than -25 dB. This is why I thought I could trust my results since the solver-log said that my results could be trusted in the frequency range of interest.

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?
