Help-me GAMBIT
 

Hi ! I'm trying to mesh a pipe (simple) with gambit but the face is twisted, why? thanks

Re: Help-me GAMBIT
 

What do you mean by "twisted"?

Re: Help-me GAMBIT
 

Sorry, but my English is not so good! A part of the meshing of the surface is moved as if it was turned.

The lines in the interface are not all parallels

Hi

It is hard to tell what the problem is without seeing the mesh. But make sure that you have the same number of nodes for every two parallel lines and the interval size is also the same. Do you have any curved faces? Have you used the Boundary Layer technique for meshing?

thanks for its aid. I am try to mesh a cylinder. The number of nodes and interval size are identical. I did not use the Boundary Layer technique.

Re: Help-me GAMBIT
 

I presume you are working with 3D now. If so, start by meshing one face, and then use the "Cooper" option to mesh the whole volume. This will give you a better mesh.

thanks a lot. Now, the problem is when I have the centre section in fluent I appear strange lines in the domain. What is this?

Re: Help-me GAMBIT
 

what type of geometry you tried to plot? is it symetric or no? I suggest the best way for this you plot a simple 2D face then draw the boundary layer and mesh the face with map mesh then sweep the surface to creat the whole volume.
