PhysicsAI ignores impact velocity but detects geometry variation
https://us.v-cdn.net/6038102/uploads/IY7KXD5G566F/crashtube-20mm.hm Hello, I have a problem regarding PhysicsAI. I have a crash tube model that is being deformed, and I would like it to generate reasonably reliable predictions for varying radii and impact velocities. I created a dataset with different radii and, for each…

[EDEM] How to Query the Torque on a Mixer Blade in a DEM Mixing Simulation?
Hello, I am currently developing a mixer simulation that mixes three types of particles. I would like to obtain the torque acting on the mixer blade, but I am not sure which options I should select in the Query settings. My current understanding is: Geometry: Torque Section: blade(IMPPELER) Query Type: Total? Component:…

E-Drive: issue on Main motor control block execute on interrupt
Dear Team, In the e-drive motor control project (open-loop and closed-loop), we initially worked with Launchpad F280049C mcu using the GANINV board, and the system was working fine….In this setup, the *main motor control is executed on interrupt, configured with *ADCBINT1 and EOC2 mode. Later, we converted the same project…

[EDEM] Restart from a previously run state
Hello, I would like to restart my simulation from a previously run state and treat it as a new initial condition. Specifically, I run the simulation for 10 seconds, then I want to take that state and restart the simulation again from 0 seconds, applying different conditions or changes from that point onward. Could you…

[EDEM] EEPA model's initial values
Hello, I am currently running a mixer simulation. I am simulating a mixer that blends three different types of particles, and I am wondering how the initial values for the EEPA model should be set. For the particles themselves, I determined the parameters using the angle of repose via the Open Powder Wizard, and I left the…

Using multiple LAMTHK constraints in DSIZE Card
Hello, I’m having a small issue with composite optimization. I need different thickness constraints on my part during FreeSize and Size optimization. The HyperMesh help site mentions that it’s possible to assign multiple LAMTHK constraints to one DSIZE card, but I can’t figure out how to do it since there is only one field…

Bushing definition in Inspire motion
I use the following python code in the API of Inspire Motion v2025.1 to create a bushing between two imported parts. I applied a force to this system and the bushing displacement was according to the defined stiffness. I use the same type of definition in a more complicated model, and the solution does not converge. Is…

Composite post-process in Radioss
Hi, I am currently working with dynamic analysis with composites in radioss and I was wondering if, as in optistruct, there was a way to visualize contours such as 'cstress', 'cfailure' or 'cstrain'. I have seen that there is an option to visualize the Tsai-Wu criterion, but I was wondering if there was the other…

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…

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…
