[GiDlist] Access to local coordinates in Tcl?

Post by Andrea Calaon »

Hello everyone,
I would like to have access to
local coordinates in the Tcl
scripts. Is there any way to do
it?

I need to know the local
coordinates of the nodes of 2D
elements which lay on the lines
boundary of the surface
hosting the element (not the
best explanation
). So first I
need to have the list of the 2D
elements with one side on the
surface boundary, and then,
for each one of those
elements, the set of local
coordinates corresponding to
the nodes on the boundary
side/s.


I could use a code similar to
the following:

In the .cnd file:

NUMBER:
CONDITION:
Line_BC
CONDTYPE: over Lines
CONDMESHTYPE: over face
elems
State: Hidden
VALUE:

END CONDITION


In the .bas file:

*set elems(All)
*Set cond Line_BC *elems
*CanRepeat


*set elems(triangle)
*add elems(quadrilateral)


*loop elems *OnlyInCond
*ElemsNum *localnodes
*end

And then read the file in Tcl,
store the data and use them
inside the Tcl procedure. But it
would be easier to do it
directly in Tcl.

Thanks for any suggestion

Best regards,

Andrea
