Products: ABAQUS/Explicit ABAQUS/CAE
Benefits: Viscous and stagnation body loads can be applied as element-based distributed loads, and stagnation pressure loads can be applied as element-based or surface-based distributed loads in ABAQUS/Explicit. You can also specify viscous and stagnation pressure loads in ABAQUS/CAE.
Description: Viscous body force loads allow you to specify a viscous force to be applied to the body. The viscous force, 
, is computed by
is the viscosity, given as the magnitude of the load; 
is the velocity of the point on the body where the force is being applied; 
is the velocity of the reference node; and 
is the element volume.Stagnation body force loads allow you to specify a stagnation force to be applied to the body. The stagnation force, 
, is computed by
is the factor, given as the magnitude of the load; is the velocity of the point on the body where the body force is being applied; is the velocity of the reference node; and is the element volume. Stagnation pressure loads allow you to specify the stagnation pressure to be applied to the body. The stagnation pressure, 
, is computed by
is the factor, given as the magnitude of the load; is the velocity of the point on the surface where the surface pressure is being applied; 
is the unit outward normal to the element at the same point; and is the velocity of the reference node. The load editor for a pressure with a viscous distribution is shown in Figure 9–2; the editor for a stagnation pressure is similar.
