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 Parameters

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.
