Sensor setup for the simulation
How does Tdelay works for /SENSOR/NOT/ in Radioss solver in Hypermesh 2025.1? I read about in solver help and it only says Time delay. What I want to set up is to apply velocity on a crush plate untill the require force is reached and stope after a time delay. So, i set up the velocity to work untill the force is reached…

MINDIM calculation in optimization model
Hello, I am conducting an optimization run with Optistruct. The MINDIM size parameter of DTPL is calculated, according to the Guide, from the average mesh size and must not be less than 2-3 times the average mesh size. Regarding this, the average mesh size is calculated from all model or just from the components included…

How to fix intersections ?
Dear Community, I'm working on modelling an airplane mockup for an upcoming Siemens GVT masterclass. I'm quite novel with the ALTAIR solution and following the guide/documentation, I get some intersections while doing the penetration test. The autofix doesn't seem to be working. Is there any way to solve the issue instead…

learning path
I am using HyperMesh version 2026.1, and I sometimes struggle to follow the instructions in the demos. For example, "00-Demo-1-Solution-Guide-GSHM-v2025.1" refers to the Analyze > Structural > Loads > Forces tool on the ribbon. I cannot find this command, even though all the ribbons are enabled. Is there a document that…

Coarsening Tetrahedral Mesh
Hello, I exported a 3D model with a tetrahedral mesh from Dragonfly into HyperMesh. The model contains a very high number of elements, so I need to make the mesh coarser. I first tried to remesh the 3D elements directly, but I was not able to reduce the number of elements significantly. I then found a discussion on the…

What is the most optimum way to learn HyperMesh for pre-processing of cfd?
Hi, everyone! Currently I am working on a simulation of cold plate. This is my first project in HM. Can you help me out with how I can learn HM for pre-processing? My current needs are 1D meshing, Surface meshing, volumetric meshing and quality check. Do you have like recommendations about resources and what things I…

Accelerations in the Load Summary Tool
I am interested in seeing the forces applied to a model. Since Hypermesh has the internal Loads Summary Tool i used this to sum up all the forces and moments (about the origin) due to the applied load (in a selected load collector). I was then confused by the results, because: The total vertical force was only equivilant…

HyperMesh shortcut to repeat the last used command
Hi Altair Community, In HyperMesh 2025, after using a command/tool and completing the operation, I often need to use the same command again. Is there any keyboard shortcut that can recall or repeat the last-used command without having to select it again from the ribbon or toolbar? For example, if I use a meshing or editing…

How to Generate a Coarse 3D Tetra Mesh
Hello, I imported a 3D model from Dragonfly into HyperMesh 2024.1, as shown below. The model already contains a 2D surface mesh. I am trying to generate a coarser 3D tetrahedral mesh. However, after increasing both the average and minimum element size, the number of 3D elements does not decrease significantly beyond a…
