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.…
Hello, I am electrical engineering student and I have started using the PSIM software. I have installed PSIM through Altair website and activated it using the student license key I've recieved. For some reason, all SimCoder library components are disabled (and cannot be enabled) I have added a picture below. What can I do…
Hi Altair Community, I'm currently running a vehicle dynamics simulation in Altair MotionView / MotionSolve 2025.1 using a Roadcourse Event. I am encountering an issue where the vehicle model does not track the vertical elevation (Z-axis) of the road profile, remaining completely flat throughout the simulation. Here is my…
Hello, I am trying to find the python code which could be used to set the parameters (see attached image) in the implicit meshing menu of an implicit body that I generated. I am unable to find it in the documentation. Thank you, Aashish
Hello, I am using the student license and followed the steps in the website. Its been a few months since I made the student account and I dont think I activated it before on any machine. Now the error “Error activating license: This license was already activated using different HostIDs.” appears when activating 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…
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, 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…
Hi Altair Support, I am using an Altair Student Edition license. My previous license activation was deactivated in Altair One, and I was informed that I could reactivate the student license using the same license key. However, when I try to activate the same license key on my new computer, I still receive the “different…

Hello, i am trying to make generative design with inspire i created a cad file from solidworks and saved as parasolid. When im trying to apply force from Z axial the part disappears from my screen and the forces set to 0. I have tried applying the force just from the z axial the problem appears again. I cannot solve the…

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. Now, when I try to activate the license again, I receive the following error: “Error activating license: This license was…
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…
