[petsc-users] Refinement on TS

[Amir]

Hello
To make a refinement on the solution in TS, what is a good procedure to 
implement?
I firstly, find the refined solution and built the refined DM and trying to 
reset the TS using new DM and new solution vector. However, I found it is not a 
correct way and working. Could you please help me on this? Thanks very much for 
your time answering me.

TSReset(ts);
VecDestroy(&X);

TSSetDM(ts,dm_refine);

TSSetSolution(ts,user->X);
