Detailed Description

template<int dim>
class aspect::PrescribedDilation::Interface< dim >

A base class for parameterizations that prescribe the dilation. If any Prescribed dilation plugin is selected by the user, then all of the following happens:

1. In the continuity equation, the source term is added to the right hand side. The value we put on the RHS is computed by PrescribedDilation::evaluate function and passed to assembler in PrescribedDilationOutputs::dilation structure.
2. In the momentum equation, the term grad(2/3 eta div v) is added to the left hand side. This term ensures we compute the deviatoric part of the strain rate tensor. The weak form of this term is -2/3 eta div_phi_u[i] div_phi_u[j].
3. Sets do_pressure_rhs_compatibility_modification to true (if no open boundary is detected).

If more than one prescribed dilation plugin is selected, the results are summed.
