User subroutine to define the viscosity for equation of state models with viscous shear behavior.
This test verifies that the user-defined viscosity in user subroutine VUVISCOSITY is transferred properly to the solution process. The finite element model consists of a C3D8R element and a CPE4R element with identical material properties. The viscous properties of the material are defined with a Cross viscosity model that is implemented as a user-defined viscosity. For comparison purposes, a duplicate set of elements with equivalent viscosity definitions is included to provide a reference solution.
In each case the results in the testing element match the solution in the reference element.
