MF-0052: Creating a 3D Mesh Starting from a Surface Mesh

 Previous topic Next topic JavaScript is required for expanding text JavaScript is required for the print function  

In this tutorial you will learn how to use the Flow3D Wizard to create a 3D mesh starting from a surface mesh. The size and quality of the surface mesh will determine the quality of the created solid mesh. The size of the tetrahedral elements created in the core (that is inside the layered mesh) is directly determined by the size of the surface mesh. Hence, it is important to have reasonably fine and uniform mesh on the surface.
