Detailed Description

Variable Documentation

integer, save icv

additional property

integer, save ieos

indicates the equation of state. Only perfect gas with a constant adiabatic coefficient, ieos=1 is available, but the user can complete the file cfther.f90, which is not a user subroutine, to add new equations of state.

integer, save iviscv

additional property:

  • 0 indicates that the volume viscosity is constant and equal to the reference volume viscosity viscv0.
  • 1 indicates that the volume viscosity is variable: its variation law must be specified in the user subroutine uscfpv.

Always useful. The volume viscosity $\kappa$ is defined by the formula expressing the stress:

\begin{eqnarray*} \tens{\sigma} = -P\,\tens{Id} + \mu (\grad\,\vect{u} + \ ^{t}\ggrad\,\vect{u}) +(\kappa-\frac{2}{3}\mu)\,\dive(\vect{u})\,\tens{Id} \end{eqnarray*}
