mummipappa New Member Join Date: Sep 2024 Posts: 2 Rep Power: 0	The idea: Run a channel flow with DNS a few time steps, then interpolate the results into a LES a few larger time steps and with a rougher mesh, then back into DNS, and back and forth like that. Thinking about using pimplefoam or pisofoam. Goal: See if it can reduce the computational cost without affecting accuracy to much. Why: Sounds fun to try. Dont hate. Does anyone know if someone have attempted it before or even if it can be done?
