I installed the student version 2024 R1 from https://www.ansys.com/academic/students/ansys-ls-dyna-student and then I started using the LS Dyna PrePost to follow some tutorials to get started. Unfortunately this warning message appears and after few minutes the application closes alone. I have...
To investigate cracks, the Element Free Galerkin (EFG) method can be used to eliminate mesh influence during crack propagation. To determine steady state deformation effectively, LS-DYNA provides the flexibility to switch time- stepping scheme arbitrarily between explicit and implicit. Furthermore, LS...
crack, or Q=crack and inside keyword editor I've also opted for *binaryd3crack but I'm not sure if I've used those cards properly enough as the output crack file have 0 size on disk.I'll be thanful if provided the "solution" or an alternate way out. Thanks :)(using LS-Dyna ...

For local refinement, LS-DYNA smooths out the mesh size transition from the refined area to the coarse area. 3D TET adaptivity (ADPOPT = 2 in*PART) now only accepts TET initial meshes When the auto remesher fails, you can now perform manual remeshing. ...

我发现这个帖子看的人较多,现做一些简要说明,DYNA(一般读作“代纳”)这个程序最重要的功能是碰撞的分析、大变形的分析等,这是它最开始的开发目的,但现在已经是包罗万象了。(为了更加清楚,特加上翻译)2007.1.18 LS-DYNA analysis capabilities: 一般分析能力 ...
