Split faces of a 3D Mesh - SimLab v2025.1
Hello! I need to carried out a CFD simulation and I'm using SimLab v2025.1. I've imported the mesh in the program, but I've a problem with the application of the boundary condition. For convenience, I created a very simple model (Cavity), which has the same problem. It is a simple box (screenshot), the inlet face is the…

Exporting Stored Data
I am trying to compare simulation results from parameter sweeps of antenna geometries that I cannot fully parameterize using the parameter sweep macro as the parameter sweep includes making different numbers of copies of various structures. The PostFeko macro that combines data puts the results in "Stored Data", but when I…

Split-Interactive / Split tool snaps to unintended vertex when creating perpendicular line
When using Split-Interactive (or any splitting tool (split solid by plane/line/etc) to create a line perpendicular to an existing horizontal edge, HyperMesh v2025.1 does not create the line where intended, and instead snaps the endpoint of the new line to a different existing point. In the image, the grey line is the one I…

Has SLC been updated in future versions to accept ODS TAGSETS.RTF and ODS WORD?
I'm currently using SLC/AAW 2025.1, which does not accept ODS TAGSETS.RTF, nor ODS WORD. When will be the next version to support ODS TAGSETS.RTF? I've heard rumours that it is in 2026 (year or version?). When will be the next version to support ODS WORD? I've seen no mention of this statement here, or elsewhere. ……………Phil

No load transfer between parts
Hello. I am new to working with hyper mesh (v2025) and I have trouble with getting realistic results with my model. It seems to as if there is no load transfer between the elements of my model and I dont know how to fix it. My model is meant to analyze a frame with arealoads on top and 5 fixed attachements on the bottom…

hm.Collection is very slow
Hi everyone, I need to batch-process 450 different regions. For each region, I generate from node ids an RBE2. With a Python solution (hm.Collection), this operation is very slow : for a sample of "only" 85 regions, the process takes 160 seconds (around 3 minutes) and usesa lot of RAM. However, using TCL marks in Python…

How to extract global moments of inertia and calculate impulses
Hi all, I'm looking at trying to extract impulses from bodies in a MBD model. For linear impulses this is relatively trivial but for angular impulses the need to compute the inertia tensor makes this more difficult. Currently bodies are defined with inertias given in a global coordinate system not the cm. I assume the…
