Issue with defining Johnson-Cook damage (D1–D5) in HyperMesh 2025 LS-DYNA interface
Hello everyone, I am setting up an impact simulation in HyperMesh 2025 using the LS-DYNA profile. I am working with the Johnson-Cook material model (*MAT_015) and I want to define a complete failure model using the Johnson-Cook damage parameters (D1–D5) via *MAT_ADD_EROSION. However, I am running into an issue: In the…

Free-Free run ending abruptly without any errors and output.
I am using HM 2026 student version for my model building (free free modal analysis of a university student team project. The model had SHELL, BAR, SOLID, RBE2/3, CONM2 & TIE) When I submit it for a run I am getting just the above text in my .out file. It does solve. My total node count is ~22k. It run when the node count…

How to solve the lack of PDM Data in STEP Assemblies
I have a step assembly of a connecting rod. I have imported it into Hypermesh Student Version, it has no PDM data (as it is a step file). I have created a material and a PSOLID property to assign to it, however fields like thickness are still missing, preventing me from meshing or any actual pre-processing on my component.…

Low absorbed energy in composite crash simulation
Hi guys! I'm running a crash simulation of a composite Impact Attenuator, and I got the simulation to run with, what looks to me, good contact interaction and composite failure mode. The problem is the energy absorbed during the crush, It's too low. At the beggining i thought the problem might be an inconsistency in the…

honeycomb shell thickness
Hi everyone, I'm modeling a hexagonal honeycomb core structure in HyperMesh with DYNA solver, and encountered two issues when assigning shell thickness: Problem 1: Thickness overlap/penetration at honeycomb corners- I created the honeycomb geometry as a midsurface, then generated 2D QUAD mesh.- When I try the "Map…

Hyperworks is crashing as soon as I try to load any model
Issue: I installed hyperworks 2022.3 very recently and it is installed properly. But as I try to open it and load any model, it crashes abruptly and gets closed without any error message. I uninstalled and re-installed many times. But still, it is not getting resolved. Probable reason: Few days back some folder related to…

I am having trouble importing CAD files into HyperMesh.
Hello, I am having trouble importing CAD files into HyperMesh. Until last year, I was using a license provided through my university, and I was able to import STEP files without any problem. Recently, I obtained a new student license and started using HyperMesh again, but now the CAD import does not work properly. When I…

how to add 2d ribs in hypermesh?
Hi! can anyone tell me the way to add ribs in hypermesh? my case is that I have created one midmesh of an expansion tank and the next step for me is to try to add some ribs inside to find out the best option but now I have difficulty connecting ribs and the outer surface. I have used exend and creat surface then mesh it,…

Exterior acoustic simulation of Motor to predict SPL using Surface velocity data a input?
Hi, I have a surface velocity data of E-motor/Engine generated by third party MBD solver in .pch file format. I would like to use this data as a excitation to predict the exterior noise at 1m distance microphones. I have looked at the documentation of IE, RADSND & APML methods in optistruct. Surface velocity required for…

Is there a route to dynamically update set definitions
I use sets to define groups of nodes & elements for loads, constraints, output sets etc. is there a mechanism to dynamically update these prior to a run, for example all elements with a particular property/material, or entities within a component. As I develop my model I want to spend less time checking / defining sets.

how to place pressures on ribs with opposite directions
I am trying to do a simulation for expansion tank, to save more time I am trying to do it in Hypermesh in 2d of midmesh, after the analysis of the out surfaces I need to add ribs inside but now I realize the problem of adding two opposite directions' pressure seems like impossible, is there a sensible way to do it?
