HyperMesh shortcut to repeat the last used command
Hi Altair Community, In HyperMesh 2025, after using a command/tool and completing the operation, I often need to use the same command again. Is there any keyboard shortcut that can recall or repeat the last-used command without having to select it again from the ribbon or toolbar? For example, if I use a meshing or editing…

Mesh Element quality - improvement
I have tried a few methods. Namely by selecting adjusted poor elements and utilizing mesh controls —> QI optimize elements. This has some negative effects especially on my washers, since the HEXA elements are destroyed and creates more work. The edit elements, auto quality and rebuild(namely flow guidelines) have no effect…

Generation of a laser weld (L-Type)
I have two components that are pressed against one another and are attached using a laser weld (l-type). The mesh should not be changed, and one is meshed as a 3d solid section and the other is a 2d shell section (type:planar section). I cannot realize the weld or give the depth and width of the seam weld when using the…

How to imprint a surface mesh from a pressed assembly
I have a surface mesh on a component that is pressed against another surface. I would like to avoid creating contacts between these two parts and want the mesh to be imprinted onto the unmeshed surface. When I try this with imprint it cannot fulfill my aim as the unmeshed geometry is a CAD file. What are some workarounds…

How to Solid Mesh the Jacket of a Bullet
Hello everyone, I'm trying to make a ballistic perforation analysis on LS-Dyna program. In this analysis I need to use a 7.62mm bullet and for those who don't know modern rifle bullets have a core and a jacket that is surrounding the core. Both of them have to be different solids because jacket is generally made out of…

Part Browser Rep Creation Material Assignment?
In HM 2026 i am using the LS-Dyna Profile (not sure if that has anything to do with my issue). I understand that within the part browser now upon creating a representation, let's say the "common" rep from CAD rep that the new common rep will have a material assignment that is driven by the "PDM material" PDM Data field for…

How to set a variable/constant value in AI Studio?
I´m new to this software, and I come from a programming context. In normal programming languages, a variable is defined by variable name, data type and value. For instance: int x = 10; Now I read that the Macros operator is kind of a substitute for that. What i do not understand is how come i always need an input for my…

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.
