When I try to log in through Altair One, I get an invalid license error. I don't know why. This is strange, since the rest of my team had no problems accessing the software using this method.
I have particles bonded in the shape of a beam, and I want to apply force to specific particles so that the entire beam experiences deformation because of that force. Currently, in the Creator section, I only see the option to add geometry and assign motion to it. But what if I want to impose motion/force directly on a…
Dear Team, In the e-drive motor control project (open-loop and closed-loop), we initially worked with Launchpad F280049C mcu using the GANINV board, and the system was working fine….In this setup, the *main motor control is executed on interrupt, configured with *ADCBINT1 and EOC2 mode. Later, we converted the same project…
How to use LTspice (.lib) models in PSIM. For example I want to use an Allegro current sensor ACS772 (.lib) model, then how can I use it in PSIM?
I previously exported X and Y coordinates along with RF Power from a simulation I ran, but I need to export the Z aswell for all X, Y points in the database. I don't mean Z as in my defined solution height, I want the height at every point (height of buildings, vegetation…). Thank you, Carlos
In FEKO, I have created a wire helix with diameter of 4 inches and 5 turns (1 inch per turn). I want to plot the S-parameters for this simple inductor, but everytime I plot them, S1,1 is 0 dB or slightly positive at 1 dB. I have added straight lines to each end of the helix coil and made these lines each a port. This is…
Hi there, after finally fixing the HOST-ID issue I was receiving, I now have this run-time 381 error. I've uninstalled and reinstalled more than 10 times now. I've deleted the cnf file every time, and there is no inf file from what I can see on my end. Tried installing older versions, and I'm getting the same issue. If a…
Hii, I want to perform a heat source at constant temperature moving on a body, I need to determine the effect of heat on the body, There is a tutorial in radios but it ain't in detail, Suggest me some methods, if its possible in optistruct that would be great The heat source moving at the defined and the heat transfer…
Hello everybody When exporting data is it posible to modify the queries in one simulation and then use the dgf file to export the new set of variable with other simulations? I tried both copying the base dfg file to the location of another simualtion and importing it, and, running a btach file with just the export command,…
Hello, I have spent hours trying to fix a weird licensing issue with my PSIM application. I have used PSIM in the past for electrical engineering courses, but for some reason, it refuses to work for me now… I have spent hours upon hours trying to fix the problem, but I am still having lots of resistance. I am desperate,…
Hello everybody When extracting data for the energy loss variables (total, normal, tangential), if the value is negative is it because it has a dissipative behavior? Or what is the correct way to interpret energy loss? Thank you.
Hello, I am using Altair Inspire 2026.0 (before this 2025.1), I started having this problem in Altair Inspire 2025.1. Whenever I start a topology optimization the simulation will fail at 58%. After that I get Error3423 with the message contact Altair Support. This problem only occured after a while, before this i could run…
