Hi,
Could anyone help me with this problem of meshing. I need to observe the pressure and velocity distribution at the surface shown in the figure... The part 1 is rotating as well as the outer cylinder is also rotating..how should I divide the part inorder to obtain the right answer.. |

Split cylindrical Tank with the other.
Then ask you, if you want to use MRF or Moving Mesh http://my.fit.edu/itresources/manual...e365.htm#68192 If you are using interfaces, then you need to disconnect your volumes. For that (once you did the split) you can copy the outer volume which rotates with 10rpm with a translation's vector, then delete the original volume (not the copy). Take the advantage of this view to apply interface BC to both volumes (one interface-BC for one volume >> meaning you need 2 interfaces because of 2 volumes). Now move the copied volume with opposite translation's vector. Both volumes should appear as earlier, but they are now disconnected (and you already defined interfaces)

Quality of mesh is not good enough. Put boundary layer on tool and other important surfaces. If possible make the hexahedral mesh.
-mAx- suggestions are valuable and accurate PS Ijaz sent me files privately Last edited by Far; February 8, 2012 at 09:09. |

Sir,
Yes, the problem is because of meshing...could you help with the boundry layer, on the algorithm and the edge/face I should select for the same..i am finding it tough to mesh the part..pls suggest step by step..i would be grateful to you.. I did as you said for the interfaces max ..but bec of quality of mesh the results are not coming... |
