Basics : Mesh Size

This LS-DYNA simulation is a simple modification of the flow around the cylinder example. Another part is created within the fluid volume. The nodes of this part are then added to the volume mesh using MESH_SIZE. This method is the most robust way to define zones within the mesh that need to maintain a finer element size. Alternatively, a quick method to define a specific shape where a certain element size has to be maintained is through the use of the MESH_SIZE_SHAPE keyword. The user is encouraged to try both methods and to observe the differences between the two meshes generated.
