Dear Community,


in the last weeks I was looking for a solution to create a moving cylinder in a refined mesh through a bigger mesh. While setting up the case especially the mesh I´m having quiet some difficulites.


At first blockmeshDict ist used to create the basic, bigger mesh (A).

After that I use TopoSetDict to create a region inside A.
Then I set up my cylinder in a subsetMesh with "subsetMesh cylinder -patch hole -overwrite". Basically a cylindershaped form is being cut out.

Afterthat i run topoSet again and finally I create different cellIDs with setFields.


My Problems are:



a) The cylinder itself has cells from the bigger overall mesh, see Image 1, what is not wanted.



b) The contour of the clinder is in steps, not like a nice arch like in blockMesh.



It can´t be that complicated, but I just can´t figure it out myself.


Maybe some of you knows how to solve this.







Thanks,


Felix
