the problem seemed to be that there was more than one meshed region. by increasing the radius in autogrid to 1 I got a single meshed surface and the problem was solved. apparently isosurface is not happy with a set that consists of more than one region. is there a way to connect sets or is increasing the radius in autogrid the only solution to this problem.
