Special GiD commands related to local axis
correct_local_axes_with_lines nodes|elements <groupList> <groupLinesList>
To use this command must apply to some surfaces local axis automatic.
When generating the mesh each element will have a local axis with z' pointing to the surface normal at the element center, but the axes x' and y' will be arbitrary set parallels to a direction,
and maybe this automatic x' direction is not appropriated to be used for example to define the fibers direction of a composite material.
It is possible to select some auxiliary curves to generate an approximated interpolated field of directions,
nodes: to correct the current local axis on the nodes of the mesh
elements : to correct the current local axis on the elements of the surface's mesh
<groupList> a list of group names with the surfaces with applied local axis automatic that want to be enhanced in its mesh (nodes or elements)
<groupLinesList> a list of group names with the auxiliary curves
e.g.
set num_enhanced [correct_local_axes_with_lines elements [list my_surfaces_group] [list my_lines_group]]
