Hello
Following my previous posts about Physical and space frames here is an example of a structure I have just finished analyzing, file ciel5
You can see the difficulties by looking at the Physical Line "bolts" and "pin" which as their names mean are connecting bolts and rotational free pins.
I did that with the function removeDouble
They are so small that could be easily selected with the nearby element in an other group.
In the design process of such a structure one keeps adding members to the frames sometimes they cross each others, a connecting point would be useful
The function intersectTwoLines might be useful
removeDouble
is an example of a function remove all the elements of a Physical "b" from a Physical "a" to create a new one named "a_claened"
however strange things happen to the Physical names
see the comments in the file.
intersectTWoLines
is an example of a function creating points at the intersection (or pseudo intersection) of two straight lines
This function is very useful when one wants to add new members crossing each others to a given space frame.
Consider adding something like it to Gmsh??
Note:
The "ciel5" example is a real life structure.
It is the stage or room of the major event of the "Festival d'Avignon" ( in july2009) named Ciels of Wajdi Mouawad.
Due quote of Gmsh will be made in the mandatory design calculation documents.
