cs_cdofb_predco.c File Reference

Build an algebraic CDO face-based system for the Navier-Stokes equations and solved it with a prediction/correction algorithm. A first equation related to the velocity prediction is solved and then a second equation related to the pressure correction is solved to project the velocity field into the space of divergence-free field.

Detailed Description

Build an algebraic CDO face-based system for the Navier-Stokes equations and solved it with a prediction/correction algorithm. A first equation related to the velocity prediction is solved and then a second equation related to the pressure correction is solved to project the velocity field into the space of divergence-free field.
