[GiDlist] Counting boundary conditions

[esneyder.montoya at utoronto.ca]

Hi there

Could somebody help me out in something, I am trying to count the number of
restrains in nodes and write the results down in my *.bas files, for a nonlinear
finite element program. This is the first time I use GiD and have no success so
far in doing this.

the *.bas commands of GiD count the number of nodes with a certain condition
BUT not the number of restraints, that is, if a node XX has three degrees of
freedom restrained (say a fixed support) , the *set cond estatement will count
ONE node BUT not THREE restraints. How can I count the restraints?

I am attaching a piece of the *.bas for your reference:

No. of restraints : *\
*set var restraints=0
*Set Cond Support-Constraints *nodes
*if(CondNumEntities(int)0)
*loop nodes *OnlyInCond
*format {"%4i"}
*restraints=*Operation(cond(1,int)+cond(2,int)+cond(3,int))
*end nodes
*endif

I don,'t understand exactly what's the desired value, and your definition
of the Support-Constraints condition, but your code can similar to this:

*set var restraints=0
*Set Cond Support-Constraints *nodes
*loop nodes *OnlyInCond
set var restraints=Operation(restraints+cond(1,int)+cond(2,int)+cond(3,int))
*end nodes
No. of restraints: *restraints

It's assumed that the fields 1,2 and 3 of Support-Constraints can be set only to 0 or 1, and 1=degree constraint.
