When using the BoingV2 model to construct an agricultural material root model for uniaxial compression tests, no matter how I adjust the parameters for the simulation, the post-processing compression force is still very small. The model exhibits penetration, but the post-processing compression force remains very low. Why…
Are there any tutorials or examples on parallel meshing for SimLab? I tried to create multiple bodies and create multiple tet meshes from them. I increased the no. of core used in meshing in the mesh preference tab. Though it looks like the meshes are still created sequentially based on the output. However in the…

Hi, Could you please help me with above Hypermesh or CAD files from altair?
Is it possible to have a particle factory where the particle is forced to start being in contact with a geometry surface? In my case I want a sphere to start rolling down a circular surface, but the particle is either generated outside the geometry or not close enough to the surface. Thank you.

Hello guys, I want to discuss structural non-linear analysis in Optistruct and better ways for it to converge. In my experience, 99% of non-convergence occur due to element distortion. Now, I calculate welded structures and I am usually interested in a certain area of the design, but I also include the environment which…
Hello, I have trouble selecting the right thickness parameter when applying copper to my structure : I understand the thickness parameter is supposed to be the thickness of my structure. I so have four questions : 1. In the case of a mettalic cube of side 5mm, should i set it to 5mm ? 2. I can read on the tutorial that "It…
Hello everybody In order to be efficient in my work, I asked my colleague to apply pressure on my FEM in another file .hm. I export the PLOAD in a .fem file. Then I want to import the file in my own .hm, it doen't regnonize the PLOAD4 in the file. I have the following errors : A valid element for pressure 1 was not found…
Description: 图示传动轴用键连接齿轮传动，我在optistruct中想要分析轴由齿轮啮合冲击带来的振动，请问我怎么让键的网格与轴、齿轮的键槽网格共节点？从而保证连接刚度，还有就是怎样模拟齿轮的啮合冲击通过键传到轴上，希望给出相关的指导意见以及相似的案例，谢谢 Product/Topic Name : Hypermesh2025-Optistruct-振动分析
While using Machinery extension to simulate Planetary gear drive at Motion Solve I've ran into following problem I'm interested in reaction force acting on bearing of planet gear in planetary gear drive which would be as drawing below While Planetary gear extension at Machinery tool is great since there is no body of…
