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…

Regarding the contact settings for interference fits in Optistruct
I currently have two parts with an interference fit of 0.55mm. When modeling the actual model, it was through penetration, and the mesh division was also through penetration. I set Clearance=-0.55 in the optistruct contact, but the mesh nodes remained through. Is this correct? Or do we need to manually move the grid nodes…

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…
