How can I fix this triangular mesh error 2331? Feko V 2025.1
Hello, no matter what surface or geometric body I place in CADfeko via a patch array, there's always a 832, and if I try to fix it, I get a 2331, and that can't be resolved. Only the output file shows the triangles, but in CADfeko I have no chance of getting rid of them—no help entry or AI query has worked so far. The…

How to define a multi-stage (ramp-up then constant) velocity profile for a Constant-Radius Cornering
Hi everyone, I am currently running a vehicle dynamics simulation in Altair MotionView 2025.1 . I am setting up a Constant-Radius Cornering Event. By default, the event only provides Initial Velocity and Final Velocity inputs, which creates a continuous linear acceleration (ramp up) throughout the entire simulation time.…

Subcase convergence till 0.99 of load in SimLab (OptiStruct)
Hello, i'm pretty new in OptiStruct solver and can anyone help me with my case please? The loadcase is converging only till 0.999998 of load. Is there any way how it could continue (load scale or something similar) from LoadCase 1 (Pretension) which stopped on 0.99999 (depends on DTMIN) of load to LoadCase2. Or if you can…

How can I export the contact radius from the EDEM API into a file?
In the EDEM API, I can access the contact radius and use it in my calculations. However, I would like to export this contact radius data as a separate file. My questions are: Is it possible to extract and save the contact radius (or total contact radius) as an output dataset? If so, how can I convert this data into an…
