I am also facing a similar issue as you raised here. And I have come up wit a solution. Use Shape Mesher tool in LS-DYNA. I created a solid cylinder. Lets say I have to create a cylinder of length 1 m. Then, I gave length of 0.5, gave x no of elements along circumference and y no. of elements along length. Now for the remaining 0.5, I keep the same no. of elements along circumference i.e. x but since I want a coarse mesh here, I reduce the no. of elements along length which is less than y. Using this method,  I am able to create mesh as shown below. Further I used the tools available in Element Tools like Duplicate Nodes to remove duplicate nodes at the interface and used MovCop tool to join parts into one single part. With this method, one can create a part with regions of different mesh densities, however biasing is not possible using Shape Mesher.

Hello Everyone,

If I am right, LS-DYNA is not a powerful tool for meshing. I am trying to find the right tool for meshing 3D arterial geometries in the .stl or .sldprt file format. Also, I plan to finally run the simulation on a multi-core (more than 8) platform. I would appreciate it if you could introduce me to the right tool.

Thanks,
