hi guys i need to mash a cylinder without mashing a sphere which is inside the cylinder. i have been trying to do so but every time i examine the mash, it shows i have mashed the sphere as well. please some 1 help me.

You have to subtract the sphere mesh from cylinder volume, then you can mesh the new volume. The problem is that Gambit is unable to mesh volumes with a missing part, like in this case, so you need to divide the volume at least in two parts.

Hope it will help

you need to divide the volumes i.e specify the volume of sphere and volume of cylinder and then meshing each volume seperatly

I hoope this will help

Thank you very much for your kind help. Im trying to do my final year project on gambit which is related to industrial air and vapour flow. Technically i have to create a cylinder and put a sphere at the middle of the cylinder and eventually generate a mash without being being able to generate the mash of the sphere. its been over 2 weeks im stuck at this point. I did most of the tutorials but still cant find anything similar to my problem. Just wondering if u would be kind enough to tell me brifly, how to divide a volume or may be few links to tutorials or documentation that might help. thank you very much in advance. Laura

As I think you must creat the two volumes first and then meshing them . 1-creating the vertices and edges of both spher and cylinder 2-creating the faces of spher 3-creating the faces of cylinder 4- The new faces of cylinder is found by subtract the faces of spher from the old faces of cylinder 5-creating the volumes of spher and cylinder 6-meshing buth volumes

If you search in google you can find tutorials by cornell university. The airfoil tutorial shows how you can subtract a face from another one, and the procedure for volumes is the same. You can also use axisymetric flow, it's much more simple to mesh and to solve.
