ANSYS Explicit Dynamics-Explicit Dynamics:Meshing

Uniform element size (in finest zoned regions)
Smallest element size controls the time step used to advance the solution in time
Explicit analyses compute dynamic stress waves that propagate throughout the entire mesh
Element size controlled by the user throughout the mesh
Not automatically dependent on geometry
Implicit analyses usually have static region of stress concentration where mesh is refined (strongly dependent on geometry)
In explicit analyses, the location of regions of high stress constantly change as stress waves propagate through the mesh
Mesh refinement is usually used to improve efficiency
Mesh transitions should be smooth for maximum accuracy
Hex-dominant meshing preferred
More efficient
Sometimes more accurate for slower transients
