I am doing cfd analysis in a filter considering laminar flow .During mesh process with coarse the meshing was successfully but when changed to normal or coarse i am getting error as ''An empty cavity is generated''. In one of the comsol discussions threads i studied about this error but there is no change in this error.
My question is
1- how to over come this error ?
2- The solution computed with coarse mesh will give the same results when computed with normal or fine mesh ?
3-I am using free tetrahedral in mesh ,by using free triangular ,quad etc is the mesh same or there will be any differences in the mesh and computation results ?
The comsol model is attached below.
Thank you in advance
