[ GiDlist ] Surface connectivities?

[Ramon Ribó]

Hello,

Comand *GlobalNodes can have as arguments: invert, swap and swapinvert
you can play
with them.

Also, it is possible to use the command in this way:
*GlobalNodes(2)
And it will return the second node of the face. Then, it is easy to
write them in inverted
order.

Regards,

Hello,

Is it possible to alter the sense of the element connectivites within Gid??

I running some contact problems and hence need the surface element
connectivities for the contact input. The output which Gid is giving is
opposite to the direction I require.

Can this be altered within a "*Set Cond" statement where i am looping over
the face elements using "*GlobalNodes" for the surface connectivities??

Obviously, I could alter the format in the FE code, but i would like keep
the code in its original format.

Thanks in advance,
Matthew

Hi;
is it possible to smooth mesh without generate the mesh again?, sometimes i saw
elements with bad shape (triangle elements), is it possible to split elements
without generate the mesh again?.

[Enrique Escolano]

After meshing, a smooth algorithm is automatically applied.
This smoothing cannot be manually applied.
Split triangles are not available.
If the mesh is too small it is possible to move some nodes to enhance the
shape.
(see Edit Mesh-Move Node)
