Hello developers,

I am working on adding a new inlet boundary condition in acnavierstoke solver which allows user/me to define the value on each node from another set of solution, and also value on each node varies over time. In short, I would like to have something similar to timeVaryingMappedFixedValue in OpenFOAM.

I am wondering if anyone has started working on this function. I imagine the way to do it is doing all math work in a new class in pyfr/solver/acnavstokes/inters.py. To be honest, I am not very familiar with the mako template and so… I really hope that someone can give me some hints.

Best regards,

Junting Chen
