[petsc-users] TS_SSP implementation for co-dependent variables

[Manuel Valera]

Hello,

I have a set of equations which are co-dependent when integrating in time,
this means the velocities u,v,w need a component from the Temperature and
Salinity integration at the same intermediate step. Same for Temperature
and Salinity, which need the current velocities (at the intermediate time
stages) to be computed accurately.

My question is, how to feed the information of the updated temperature
inside the velocity, and vice-versa? this would be equivalent, I think, to
obtaining the intermediate stages of the time integration so they can be
the input for the next intermediate stage.

Thanks,
