How do you make a macro to sequentially solve the list of scenarios automatically?
Hello, we usually run many solving scenarios. However, we must wait until each simulation is done before continuing to the next one. Temporarily, I do it with the pyflux command. Can Altair make the macro to run it automatically? Thank you so much

Why does my part moves against gravity in Nonlinear transient once it contacts rigid mesh
Hello, I am trying to do a Non linear transient simulation on a sheet metal that contacts a rigid mesh only with gravity loading. The sheet metal seems to be moving in the right direction and contacts the part correctly, but once it has contact with the rigid mesh it moves upward and even though the solution converges, the…

Importing mesh from hyperworks to hyperworks CFD
I have been trying to import mesh that I created in hyperworks 2021 and trying to use it in Hyperworks CFD. However, I am facing issues such as I am not able to manipulate elements in it due to which I am not able to run the simulation. I have created the mesh in and saved in ".hm" file extension with two cases. First,…

How to set a CENTRIFUGAL FORCE in Hypermesh for Abaqus
Hello everyone, I'm setting up a simulation for Abaqus using Hypermesh. I have a centrifugal load, but I don't know how to set it, in the image below is shown what I'm doing now (I don't know if it's the right way tough): If it is right, I have some questions: 1)Is the magnitude the rotational velocity (rad/s)? 2)Are…

How to constrain the motion of geometry in only one direction in MBD
Hi, When I use the MBD to apply a force on geometery in z direction, I want to constrain the direction only in z direction, which means the motion in x and y direction should be limited, how to achieve this? Thanks

How to freeze elements?
1. Is there a way to freeze elements in hyperworks? If I am meshing a big part, I would like to freeze areas that are already meshed so that I don't disturb it accidentally 2. There is an option to load the user profile ( Abaqus, LS dyna) in hypermesh with a green icon. Is there a similar option in hyperworks?

External acoustic cavty meshing
Hello everyone, I'm currently working on a task where I need to perform acoustic analysis using a setup that involves a cube placed at the center of a sphere. The cube's surfaces are already meshed with 2D quads, and now I need to mesh the volume between the cube and the spherical boundary with 3D tetra elements for a…

How to get Holzapfel-Gasser-Ogden (HGO) Model?
Hello, I am dealing with finite element simulation of ligaments. I expect to perform a simulation with Holzapfel-Gasser-Ogden model, as it is commonly utilized for biomechanical models. However, what I've learned now is that Hyperworks only provides Ogden model (under MATHE --> OGDEN), which I think it doesn't resemble HGO…

Node Points after Solid Map
I completed a solid map in hypermesh and I see these yellow nodes/points that appear. They appear around a few 3D elements that have a triangular 2D surface. They only appear on a few, and I would expect them to go all the way up to the top surface, but its only at single elements. Attached are a couple photos of what I am…

Solid Map Errors
I am attempting to mesh a complex part. I was able to split the entirety of the part into a total of 38 mappable sub-parts. When I highlight the entirety of the model and click mesh, my screen says "incomplete sequenced 1/38 solids with 274/0 edge grps" and then "Meshing Failed". How do I stop this from happening?

Optistruct crash after starting an analysis with user-defined material
My goal is to create a material law that accounts for the adaptive behavior of bone in response to stress. Since I couldn't find any suitable material in Optistruct, I decided to program it myself in C++ using the USERMAT (User-Defined Material) tool. However, a few seconds after starting the analysis, I receive an error…
