contact creation
Dear all. I have a question about the contact creation. I'm trying to connect 2 meshed components(fuselage skin and stringers, already obtained their midsurface mesh). Due different thickness and materials, I can't use "equivalent" and "connector>area". And when I try to use "autocontact"it returns my parts have pwntration…

New hypermesh feature line 문의
Description: New hypermesh에서 featureline 색을 바꾸고 두께를 굵게 하는 방법이 없을까요? Appearance에 mesh line 두껍게 조절만으로는 한계가 있습니다. Mesh는 안보이게 하고 싶고, mesh line을 더 명확하게 보고 싶은 상황압니다. New Hyperview에서는 잘되는 거 같은데, Hypermesh에서는 어떻게 할 수 있나 싶어서 문의드립니다. Product/Topic Name : New hypermesh 2025.1

¿Cómo puedo hacer para que mi tarjeta de video no bloquee hypermesh?
Instalé la versión de hypermesh (Desktop 2026 (Windows – x86_64 (64-bit) – 11)) en conjunto con OptiStruct (Mechanical Solvers 2026 (Windows – x86_64 (64-bit) – 11)) pero al querer utilizar el programa de hypermesh mi pantalla se queda en negro sin opción a poder ubicar algún componente. Adjunto foto de evidencia.

2 questions: polygon algorithm (5 sided surface) + points by path
Hi, I failed finding for the "polygon" algorithm to mesh a 5 sides surface In addition, I wanted to add fixing points by path using existing nodes, but I've found nothing in all options nor specific icons: what am I missing? Note: I was used, with solid map, to clik on the "surface+elements" source, and "surface+elements"…

Non-linear static analysis run parameters
Hello, I'm new in non-linear static analysis. I've created a model in Hypermesh with Large Displacements enabled. When it is running using Altair's Compute Console and Optistruct solver, several parameters appear in the Solver View. I did not find any information about what do they mean. They are: Non1_EUI_st, Err_EPI_st,…

imprint and merge for conforming mesh (assembly)
Hi I've not found a good way to "merge" 2 surfaces after imprinting so that the mesh remains conform (see picture); note it is an assembly so i do not want to merge those 2 solids. I'm thinking in different manual ways but I'm wondering if there's an option to do that "properly". Thanks for your support Paul

Get node coordinates with Hypermesh (new interface)
Hi I've added "new interface" in the title just to say i used Hypermesh (previous interface) during about 15 years before moving to another company (5 years ago). I mainly performed hex dominant meshes on assemblies using "Solid map" (from memory) + some shortcuts like F2, F5, F11, etc :-) Today, i'm testing Hypermesh…

Segmentation Error
Hello everyone, I am using HyperMesh Student Edition 2026 on my ASUS laptop.I keep getting a "Segmentation Error" immediately after startup or when trying to create basic geometry (like circles). As you can see in the attached screenshots, before the crash, the graphics glitch (red trails appear), and then the software…

Let me describe my problem.
Let me describe my problem: I meshed my model using HM 2020. The model's unit system was cm, with a mesh size of 0.1cm (1mm). Then I learned the new version, HM 2026. After opening the meshed HM file from the 2020 version with the new version, I set Param/Criteria for mesh quality checks. However, a problem arose: my model…

Problems with hypermesh and optistruct unable to create materials or properties.
Hello, I recently downloaded hypermesh and optistruct. However I can´t really use de program. For example, I cannot create a material and add properties to it, the following image is the only thing I see. I cannot create for example beams or when I try a fatal error occurs. In addition I cannot add any other properties.…

Not gatting solution
In HyperMesh 2026 (OptiStruct user profile), my OptiStruct job completes immediately after the header with no analysis/iterations — .out file only shows startup info + empty "Iteration Subcase Variable Grid/Elem ID Value" table. No subcase processing or results. Model Browser shows: Load Step Inputs (1) SUBCASE (2) under…

Unexpected Result Nonlinear Static Analysis
Hey all! I'm doing an assignment for a FEM course in my university. The scenario has a beam in the x-axis and a moment applied in the negative y-axis at the beam tip. The issue is that the beam does not deflect as expected. Instead of the tip bending upwards, the middle of the beam starts moving upwards and then backwards…

How to Select Handles or Domains by Location When Using Morph (By Box / By Cylinder)?
I am currently using the morph function to write a script, but I’ve found that when using “by box” or “by cylinder,” I’m unable to select the handles based on their positions. If I want to select handles or domains by location, what are the common or recommended methods to do so? "by box" x0 y0 z0 x1 y1 z1 syst location…

Support Needed: Proper SOLID187 Assignment Procedure in HyperMesh 2025
Hi, I’m working with a solid tetrahedral mesh where I need to assign the SOLID187 element type and then export the model to a .cdb file for ANSYS analysis. The issue is that even though I can select SOLID187 in the sensor (element type) panel, there is no corresponding “SOLID187P” property card available. Because of that,…

Is it possible to equivalence same node numbers, from include files, while importing master file?
In master and include file, I have same node ID's at two locations (Diff Coordinates). The objective is to equivalence the same Node ID's while importing the master include file. If I import the master file, the element corresponding to the duplicate node id is getting deleted. Is there any possibility to retain the…

HyperMesh Frequency Response (Modal) Setup Using Python
Hello community, I am trying to set up a dynamic stiffness (frequency response) loadstep using Python and TCL, with the OptiStruct solver. It seems that the setup is complete in the HyperMesh GUI, but when exporting the FEM file, the displacement output control is missing. Therefore, it triggered ERROR #291. I’ve attached…
