Hey i tried to activate my key, i tried downloading 2026 s-frame and i kept getting the time error which couldn't resolve, downloaded 2025 got the same run time error 3 something and i couldn't resolve it. I deleted every file related to s-frame and some admin files now i downloaded 2026 and im getting this error.
I was trying to activate PSIM using the student license assosiated with my college email,and it didn't work, I already activated it once in my old computer and forgot to deactivate it and now I don't have connection to my old computer atm. Is there a way to remove my licence from my old computer and use it in the other one…
Hi, I tried to load the surface mesh from CFD which is in PLOT3D format. And I ran the case M=0.84, AoA = 3.06 deg with the transonic field panel method. I just ran the case without boundary-layer coupling. The pressure contour does show the Lambda-type shockwave. The surface grid is attached. Not sure whether you can…
Hi all, I am having some problems with soft soil simulation using motionview2024. I have created a ramp terrain using my own edited .crg file, but after the simulation run is completed as shown below I am unable to visualise the road deformation when using hyperview post-processing, there is no option for road deformation…
I am writing to request assistance with deactivating my student license from my previous device. I recently attempted to transfer my license to a new computer. However, I made a mistake by deleting the Windows user profile and resetting the old computer before deactivating the license within the software. Since the old…
Hello Altair Support Team, I am a student at PSG Institute of Technology and Applied Research. I am trying to activate my Feko license, but I am receiving the error: "This license was already activated using different HostIDs."

Hi I am trying to use a custom subroutine to calculate a custom contact interface between two objects I have an issue connecting the starter and the engine runs. In the starter run, im assigning the memory allocation (USERWIS_INI) and values (USERWIS) for IUVAR and UVAR while maintining all other values as Radioss assigned…
Hello, I have a question concerning the near surface field values in FEKO. I understand that FEKO is computing surface current and make them radiates with Green function to have field in space. When I ask the field value near a surface, I can see the field growing as 1/r. This is expected since this is the formula for a…
Hello Community, I have recently completed a 2D Transient Magnetic simulation in SimLab for a high-speed motor. My goal is to determine the final output power, but I am seeking clarification on how the flux solver handles different loss components in relation to the calculated torque. Setup & Results: Software: SimLab 2D…
I previously activated my Altair Student license on another PC. Now I have changed my computer and cannot deactivate the license from the old machine. Please reset my HostID so I can activate the license on my new PC.
Hi, I am currently working on a 2D transient magnetic model of an electric motor in SimLab. I am trying to model the stator winding using a Litz wire representation. Here is what I have done so far: Created the motor geometry in 2D. Constructed the Litz wire cross-section (multiple strands inside one slot). Merged all…
Hello, I previously activated my Altair license on an old computer, but I no longer have access to that machine and could not deactivate the license. When trying to activate on my new computer, I receive a message that the license is already registered on another system. Could you please reset or deactivate the license…
How do i create a sinusoidal a path for an axial flux machine to estimate for the magnetic flux density ?
Hi, I’m working with a solid tetrahedral mesh where I need to assign the SOLID187 element type and then export the model to a .cdb file for ANSYS analysis. The issue is that even though I can select SOLID187 in the sensor (element type) panel, there is no corresponding “SOLID187P” property card available. Because of that,…
