TSComputeTransientVariable#
transforms state (primitive) variables to transient (conservative) variables
Synopsis#
#include "petscts.h"
PetscErrorCode TSComputeTransientVariable(TS ts, Vec U, Vec C)
Logically Collective
Input Parameters#
ts - TS on which to compute
U - state vector to be transformed to transient variables
Output Parameter#
C - transient (conservative) variable
Developer Notes#
If DMTSSetTransientVariable() has not been called, then C is not modified in this routine and C = NULL is allowed.
This makes it safe to call without a guard. One can use TSHasTransientVariable() to check if transient variables are
being used.
