Description: My company is looking into using software for EMC (radiated susceptibility/emissions and conducted susceptibility/emissions) and thermal testing of PCB assemblies to prevent added costs of redesign and retesting. I am uncertain exactly what the differences are between some of the programs and what all the…
Hi, I am working on an analysis that involves high stress and strain in the material. I have assigned non-linear material with material curve defined through TABLES1 and assigned at MATS1 in the material. following is the error I am getting: I am using Optistruct as a solver. Can anybody help me with this? I have used…
hi, i can't view the hyperworks downloader on the site, a friend of mine said me that is a license trouble, because i changed my pc and the the license is already active on that device, so i can't download again it. How can i do?
Hello everyone, i have to create a timedependent 3-point-bending simulation. I created a table with a constant displacement for 10s, but the simulation doens't start.. There are fixed spcs for the fixed cylinders and one spc (with dof 1 in x direction), which are combined with a spcdadd. I also created a spcd for the…
In earlier versions, it seems there was a "reverse zoom direction" check box in mouse controls settings in preferences. There isn't one as far as I can see in 2025. How do I reverse the zoom direction
Hi everyone, I'm currently working on modeling adhesive contacts in RADIOSS and I'm trying to implement a Cohesive Zone Model (CZM) to simulate the adhesive behavior between surfaces. Has anyone here worked on a similar problem or could point me to some useful examples or best practices? Any guidance or shared experience…
I'm working on a project that involves performing the Double Lane Change event. After building the vehicle model, I made sure there were no errors, and then I configured the Altair Driver and the event with the specific parameters I needed. However, when I click Run, the simulation stops immediately before starting,…
Hi, i'm a beginner at mbd simulations, and I want to understand some things about motionsolve and the fsae model that altair gives to us. I imported the standard model, but it doesn't match our CAD model, so i'm wondering if there is a way to import our assembly to this model, or even to motionsolve somehow? Or, how can I…
I already named the result file (.h3d) and the solver file (.rad) with the same name, but I still encounter that error during training. Can anyone tell me how to fix it?
Hi I am trying to perform analysis that consists of beam elements attached to tetra elements. Beam elements are generated from lines, after the beam elements were created I can see in the FEM file that there are elements with zero length therefore causing me the ERROR 1026(same node id). (if my understanding is correct).…
