I'm using the student version of Altair SimLab and I'm trying to create a co-site interference simulation. So far I've followed along with the official Antenna Placement and Cosite Interference tutorials: Antenna Placement Co-site Interference The problem I have is that I'm stuck on creating a Cosite Interference solution.…
In the EDEM software, is it possible to use a particle-bonded model as an equivalent substitute for a complex rigid body? My primary application involves CFD-DEM simulations. The key requirement is to accurately determine the total fluid forces and torques acting on this complex rigid body within the flow field using this…
Hello, I have been working through the tutorial ACU-T 6103: AcuSolve–EDEM Bidirectional Coupling with Heat Transfer. In my case, particles are in contact with a hot wall (~600 K), and I would like to include radiative heat transfer effects on the particles. I noticed in the AcuSolve 2026 release notes that a new feature…
I am attempting to import a data file, but need to set custom field lengths as the fields may sometimes be longer than what Monarch (2025.0, 64-bit) is defaulting them to. However, every time I move to a new field, it reverts the previous one to the original default length assigned by Monarch. This is maddening. Is this a…
