[petsc-users] TS prestep function

[Christian Peco Regales, Ph.D.]

I have started to use the TS environment to solve a diffusion problem with XFEM in which, at the beginning of every step, a number of values have to be recomputed in order to properly fill the Jacobian (e.g. change some quadrature weights). However, I see that the the function is expected with the format func(TS ts), with no possibility of getting a user context to perform the computations I need.


Is there a way to get around that? Thanks!


Christian
