[petsc-users] Query regarding old PETSC version

Hi, Due to legacy issues, I am working with tversion 2.3.2 of PETSc in FORTRAN. I want to monitor the true residual and hence I tried to use the function KSPTrueResididual(). However, I am unable to understand what kind of pointer is the last input parameter, "*dummy" supposed to be. I could not

[petsc-users] accessing fields from previous, converged solution.

Hello, I have a problem with several fields that I solve with PetscFE and TS. I now need to access the solution from the previous timestep to compute the residual for the current timestep. I tried a TSMonitor with the following code in it: TSGetDM(ts,); DMClone(dm,_aux); DMGetDS(dm,_aux);
