Default GAMBITcrash

Hi all,

I'm having problems while meshing my geometry in GAMBIT. I'm trying to use sizing functions. For the moment, I'm trying to specify a very coarse mesh using the sizing function just to see how the mesh looks. But whatever I do, GAMBIT crashes and the message displayed says that a fatal error has occured. Also, it says that some of the faces could not be meshed. When I try to mesh according to the heirarchy (i.e. edges, faces, volume) too, the program crashes.

Does anyone have any suggestions for me?

Thanks, Vidya

Hi Vidya,

Did u check whether there is/are any common face/s in ur model. If there is a common face(shared by two volumes), generally gambit doen't mesh it properly. So check it once

Hi Madhkar,

There are some common faces in my geometry. This is because my model is enclosed in a cylinder and I subtracted the volume of the model from that of the cylinder to get the flow domain. So I think that's where the common faces were created. But how do I do away with them? Will they affect my geometry? Or is there any other solution?

Thanks, Vidya
