Hi all,

I would like to find out if the following workflow I have in mind is feasible to implement in Aspect at the moment. So for every time step, this basically happens:

- Solve the Stokes’ equations with one set of boundary conditions (BCs) over the whole domain to obtain one set of velocity solutions (let’s call this
*A*). - Use
*A*to perform some calculations to get a second set of BCs. - Solve the Stokes’ equations again but with the abovementioned BCs to obtain a second set of velocity solutions (let’s call this
*B*). - Combine
*A*and*B*to advect the relevant fields to the next time step.

I am interested to find out if such a scheme is supported at the moment by a plugin for instance or will it likely to involve heavy tinkering to the simulator if it is not.

Thanks,

Kang Wei
