Join us for a community conversation on Simcenter PSIM, designed to help engineers and simulation users overcome common challenges when building PSIM schematics and running simulations. Many issues labeled as "PSIM Solver Issues" are often rooted in controls design, model definition, setup, or general simulation practices.…
I am writing to request help with activating my PSIM Student Edition license. When I attempt to enter my Activation Key in the Altair License Utility, I encounter an "Error: Unable to access license store" message under the License Store dropdown, and the "Activate" button remains grayed out. I have attached a screenshot…
Hello, In FEKO, I can ask for a far field computation, and see the E field value. However, the E field I presume decay as 1/r. I see a value of 32mV maximum in my 3D pattern. → At which distance this pattern is computed ? At the definition of the far field ? Thanks !

Hello, I have a trajectory and I wanted to specify it above mean sea level, or independent from the terrain. Switching choice from this menu has no effect and the trajectory is systematically interpreted above ground. What could be the reason? I use v.2026. Thanks, Nicolo'
Hello, Simulating the propagation of a phased array antenna into a rural environment, I imported the far field from Feko to Winprop Proman. I see that Proman discards information concerning the far field phase. In other words, it retains only the magnitude out of the complex Feko far field data. I could retrive this…
So far one has to go to 3D to see an overlayed map (tiff, or bmp of the area under study). Can this be done simply in the 2D viewer as well?
Hello Altair Support Team, I am using the PSIM Student Edition. My student license was previously activated on my computer, but the computer was formatted/reset before I could deactivate the license.

Hello. I previously requested a license reset because I formatted my laptop and lost access to my old account (I didn't follow the necessary procedures), and I was able to use it perfectly after that. However, I made the same mistake and can no longer use PSIM for the same reason. I have my license, but it isn't working…

Hello, I am running the same simulation in LTspice and PSIM (AC Analysis), but I am getting different results between the two simulations. I would like to understand where this difference could come from. It is also possible that I have not fully understood how the Parameter Sweep block works in PSIM, so I would appreciate…
