Yes transforming uses Jacobian. So you're using multi-grid? Or chimera/overset grids?
@zbeekman Giacomo used a kinda of multi-grid (non dynamic/adaptive grid refinement), I am using dynamic overlapping grid (Chimera) with also multi-grid acceleration, but the point is that we want to have:
- multi-grid residual acceleration;
- AMR (dynamic/adaptive mesh refinement);
- dynamic overlapping grids (Chimera with moving bodies);
- initially based on structured (body fitted) blocks but at same point we want:
- mix also unstructured blocks (to easy mesh region of low interest);
- mix also immersed boundaries;
- track sharp interface between:
- same fluid with different state or phase;
- different fluids:
One crucial point (among others) is doing interpolation with very different solutions computed on the some region.
@zbeekman And how you evaluate Jacobian elements? I refer to the derivatives of the physical coordinates respect to computational coordinates, or vice-versa.
