Default oscillating divergence
Posts: n/a

Im trying to run a free surface simulation of the free surface flow over a cylinder using a combination of MAC and SOLA.

My problem is that my divergence does not decrease beyond a particular value say about 0.019(my criteria for convergence being 0.001) while at the same time the solution doesnt blow up either. It just oscillates around this value.

Could anyone tell me why this is happening please?

It could be rounding errors. Have you tried running in double precision?
