I have used ICEM to generate a mesh for Y shape vessel. The "vessel wall" volume part was generated via the prism layer throughout the whole vein surface. However, the two branches of the vein (colored green and purple) have different material properties and the prism layer only created one volume part. Is there any way I can split the prism volume part into two parts in ICEM?
I have also tried to generate the prism layers for the two branches separately and then merge, but there is connectivity problems with the new mesh.
