    Create the edge initial velocity boundaries on the edge groups. The velocity will be applied only at the initial.


    **Parameters:** 
        **nodal_tag:** tag of the group
        
        **normal:** (default free) Edge velocity in the local normal direction or the amplitude of n table.
        
        **shear:** (default free) Edge velocity in the local shear direction or the amplitude of s table.
