Hi,

I would like to export the linear part of the connectivity of a quadratic 3D
mesh using 20-noded hexahedron. In other words, just the vertex nodes.

The linear part will be used for mass transfert using finite differences and
the obtained results transfered to a mechanical finite element problem using
the quadratic mesh.

Thanks

Daniel Marceau

In GiD the element nodes are ordered first the "linear part", and then the
quadratic nodes (hierarchical numeration)
for example, for a 20-noded hexahedral, the corner nodes are the first 8
nodes.

For example, you can print only this nodes using a bas template like:

*loop elems
*elemsconec(1) *elemsconec(2) *elemsconec(3) *elemsconec(4)
*elemsconec(5) *elemsconec(6) *elemsconec(7) *elemsconec(8)
*end elems
