When solving the Navier Stokes Eq. (with a meshless solver): what is the most efficient way you have found to correct de velocity field to account for the pressure field constraints, e.g., for incompressible (div of v = 0) or Low-Mach thermal flows (divergence defined through the energy equation).
I'm interested in knowing your opinion regarding the most convenient methods (e.g., efficiency, ease of implementation in complex scenarios, accuracy, and so on) when implementing in-house solvers. I am sure your opinions will differ due to many factors. Please write your research area and any important details behind your decision (e.g., you value ease of implementation over accuracy).
