Prism layer around cylinder
 

Hi all,

I am new to STAR CCM and i was trying to mesh a simple geometry of a cylinder in a fluid domain. I could successfully do everything. From geometry to getting refined mesh around wake region.I have used surface remesher, trimmer and prism. I have tried every single value for the prism layer but it just would not come. I tried doing the example cylinder problem and in that when i change the parameters i am able to change the prism too. But this does not happen in my model, its not even appearing. Can anyone please help?I have lost half a day trying to get it. Please guide if you can.

Thanks
Arun

Got it. I had actually kept the symmetry boundary condition as wall. I just changed it to symmetry and it worked. Can anyone please tell me why is it so? I mean i was working on ICEM and FLUENT but never had the boundary condition of a region affecting its meshing. Sorry if its a silly query, i am not able to justify.

Thanks.

Regards
Arun

Just make 2 section plots and you will find out ;-)

2 section plots? i did not get..Can you please elaborate?
sorry

Just create this section and look at the mesh. The prism layer goes around the corner and is not visible from the outside.

Thanks a lot. :)..
