yet anoither mail about my solver (incompresible, Navier-Stokes, MAC method).
its work correctly ALWAYS for big viscosity. problems are, when viscosity is smallest than 10, like 0.01 (uhhh...).
that looks, than stability criteria are miss, but anyway its not good way to correct this i think - makuing stronger stability criterium do not help. anyway, my question follow:
what is important to setting good values in my program (i. eg. values of GY, vis [viscosity])? let say GY=-9.8, then viscosity = 0.01. When i change GY to 0.98, then viscosity also must change to get real effects?
