Applying concetrated forces in radioss
Hello, I want to ask how do forces given as a function of time F(t) work? For me they work unexpectedly because, when I make the input for constant force, the model doesn't come to a rest but keeps moving as if the force keeps adding up. I run it for 500ms at 100ms i keep getting increased internal energy when it should…

Does Altair Inspires "faster" optimization use tetrahedron of first order or second order?
Hello, the FE-analysis of Altair Inspire distinguishes between first order and second order thetrahedrons. (faster / more accurate ) Is it the same for the topolgy optimization ? If that is the case and Altair Inspires suggests than one should use the faster solution (first order thetrahedrons) for topology optimizations…

Huge difference in Displacement and Mises Tension for Body vs Surface Part Analysis
Hello, i have a question regarding a surface vs body analysis with Altair Inspire. 2022.2.0. The part is basically a huge curved plate which I believe allows me to use the midsurface to create a faster FE-analysis. But as I cannot do any topology optimization on a surface part i need the body. Therefore i just wanted to do…

How to use volumetric flow (m^3/s) - outlet boundary condition
Hello all, I am new to the Altiar ecosystem and trying to model a basic binary flow diffusion/multi-species problem wherein air and gas are mixing. The simplified system is represented as a box with two inlets and one outlet. For the first inlet, I have flow rate data of air (100% air and 0% gas) entering the system at a…

PSIM version and AC sweep problem
I've got a project about Buck converter and 3p3z compensator with DLL. The project's version is PSIM 9.0 (x86) and DLL (win32). The bode plot of the product owner is good and reasonable. When I run the project on the version that I've got in Altair one education one year version, the result is terrible. I've checked the…

Modal analysis for Pole structure supported by preloaded cables
Hi all, I would like to perform a modal analysis for a simple pole supported by preloaded cables. For the cable behavior, a possible solution is to consider the CGAP elements. However, I couldn't consider this option for the linear modal analysis due to the non-linearity of the CGAP. To better explain the test case I have…

How to use the PSIM On-Off Controllers
On the Library browser we find two switch controllers, the “normal” On-Of Controller, and the On-Off Controller (multi-level). The multi-level controller contains the “normal” controller and other multiple combinations of inputs and outputs and should be chosen according to the application. The multilevel switch can handle…
