TSTEP tab error in HyperMesh
Hi, Iam doing a transient heat transfer analysis in Hypermesh 2024.1. I have a question about the TSTEP definition. When I write the TSTEP card in 4–5 lines, I get the following error: *** ERROR #1031 *** in the input data: Too many continuation cards. When I reduce TSTEP to only two lines, this error disappears, but I get…

Geometry exportation erros
Hello. I am trying to validate by myself the NACA 0012 airfoil from the tutorials. But I am trying to make myself the geometry of the problem in order to be able to change the geometry at some point in the good way (in case I want to study anything else than an airfoil). I am using Fusion 360 to create the geometry and…

nodes merging
The image shows two 1D and two 2D elements that are disconnected. Nodes 2-3 for the 1D elements and 2-5 and 3-8 for the 2D elements are very close or overlapped. How can I merge these nodes to restore the connection between the elements? If there are many nodes to merge, doing it manually is time-consuming. Is there a…

Is it possible to script a fully parameterized model (geometry + mesh) in HyperMesh with Python?
Hi all, I am trying to learn how to automate a complete workflow in HyperMesh using its Python scripting capabilities. My objective is to fully parameterize the creation of a 3D object. This would involve scripting the following steps: First, generating the 3D geometry based on specific dimensions (width, length, height).…

How does Hypermesh order its surface ids?
I have a step-file of a simple cuboid. Within it, there's the CLOSED_SHELL parameter (Entry #16) referencing the six faces that make up the cuboid. I expected Hypermesh to assign Surface IDs based on the order these faces appear in the step-file, but this doesn't seem to be the case. The two smaller square ends of the…

Surface not splitting correctly
I have a fairly simple 2D-Geometry of a C-Clip base shape. Whenever I try to split this surface along its center line, a fresh cut line appears, but the surface doesn't actually split, in the sense that selecting one half automatically selects the entire part. This only happens when I split the part along y=0, other…
