set normal [GiD_Info parametric surface surface_id normal v]
=20
To know the u,v parameters of a point with coordinates x y z =
(located on the surface), must use
set uv [GiD_Info parametric surface surface_id uv_fromcoord x y =
z]
=20
Read GiD help about Cutomization-Tcl/Tk extension-Control =
functions-Info function
=20
As user, you can also know the normal of the surface on a point from the =
menu
Utilities-Id=20
then click the righ mouse button ,and select in the contextual menu =
"Normal in surface"
and click the desired point on a surface. The normal x y z will be =
shown in the lower message bar

Subject: [GiDlist] Surface normals at any point
Dear GiD Team,
I need the normal to a surface (NURBS in general), at a point that
clearly is on the surface itself (the point is obtained as an
intersection between the surface and a line). Is there any way to =
obtain
from the GiD database through Tcl such information? I have seent that
for parametric surfaces this has been implemented.
=20
Best regards
=20
Andrea
