4-Terminal MOSFET Model in PSIM
I would like to ask whether PSIM provides a 4-terminal MOSFET model with separate Gate, Drain, Source, and Body (Bulk) terminals. I have checked several MOSFET models available in PSIM, including the built-in MOSFET models, and they all appear to have only three terminals, with the body terminal internally connected to the…
How to retrieve a multi-material mesh with OSSmooth
Description: Hello, I am running multi-material topology optimization in OptiStruct and I want to retrieve the results into HyperMesh to run validation analysis. Is there a way with the OSSmooth tool to get a unified result but with mesh distinction (not different size but different component assigned or property) for each…
Is there a way to couple all material properties to density in multi-material topology optimization?
Description: Hello, I am a student doing a master's thesis on multi-material and multi-objective topology optimization. I have successfully done both separately using Altair Hypermesh and OptiStruct, but now I was trying to achieve multi-material multi-objective topology optimization. I am trying a thermo-mechanical…

Request to reset HostID for PSIM Student Edition (PC breakdown)
Dear Altair Support Team, I am writing to request a HostID reset for my PSIM Student Edition license. I recently had to install on other computer since the last had breakdown, which caused my system's HostID to change. When I try to activate PSIM again using my student license, I receive the following error:"Error…
Altair slc running ubuntu linux from windows using ms wsl
Altair SLC running Ubuntu Linux from Windows using MS WSL WSL is not just useful but highly valuable for serious Linux and Python development on Windows 11. It effectively solves the "Linux-first" problem that has historically plagued Windows-based developers and data scientists. Much better that dual boot. Especially…

the H3D file only contains the files of the flexible body shafts and does not include other componen
Hello, in the result file loaded from MotionSolve in HyperView, there are three broken shafts inside the excavator bucket. We will convert these broken shafts into flexible bodies and replace the rigid shafts in the entire model file with Flexbody H3D. In MotionView, all components can be displayed, and in HyperMesh, the…
Inquiry About Synchronizing Particle and Geometry Motion When Using the Fibers Bonding Model
We are considering conducting an analysis in which the motion of particles and geometry are synchronized, similar to the toothbrush simulation shown at the URL below. However, since the Fibers Bonding model relies on Meta-Particles, we are having difficulty establishing a bond or synchronized motion between particles and…
Is it possible to re-mesh a solid/part without having to reapply loads in HyperMesh?
Description: As the title suggests, is it possible to re-mesh a solid or shell part that has SPCs and RBE2s etc already attached?
