Hello Everyone,
I need some help in meshing a cross section of a car door seal with hypermesh. I am new to this so it would be great help if someone guides me. I can share the iges file. My email id - bhushan470@gmail.com.
Thanks in advance.

Hi bhushvk, first I've moved this topic to the Hypermesh forum (bear with me as I get this place straightened out). So if you have an .iges file, the first thing to do would be to make sure that the surfaces of it are divided to have two large surfaces and a middle area along the narrow portion. Think of it like a rectangular prism. What you are then going to do is 2D quad mesh one of the larger ends surfaces to act as a "source" mesh for the hex mesh to eventually match. You can do this in the 2D tab -> automesh. Once you have the 2D quad mesh go to 3D -> solid map and select the geometry and then select the 2D mesh as source, and the far large surface as the destination. You should be able to interactively define the number of through elements for the solid mesh by clicking on the edge once you get this all working. Let me know if you get stumped.
Hi Admin,
Thank you very much for the reply. Your videos are very informative and it helped me a lot as I want to run this model in ls-dyna. Please make more videos. If possible implicit Analysis, someting with MAT_181, Simplified Rubber.
I tried the procedure you explained for hexa meshing and it worked great. I used the drag option and created elements along the geoemtry by specifiying dimensions, I hope that is right as well. Now stuck with some elements that are having high quad-angles.
Thank you again. 🙂 🙂
I forgot to mention that using "Multi solids" under the solid map tab is what you should use for the mesh to follow the shape of the geometry. You would select the solid, and the source surface of the 2D mesh, and the desination surface. Then you click mesh and can click on the edge to define how many through elements you would like. You can use drag, but it will not follow the geometry curvature and will only mesh in a straight line from source to destination.
