When I run the simulation, I see that my sphere model has striations or some kind of pattern over its surface. Its not a smooth sphere. I am not able to correct the mistake- I tried different meshing techniques. Either the meshing fails or I get very coarse mesh. Any help in this topic will be appreciated.
