Alingned Node Coordinate Value (TCL Script)
Hi,
How can I determine the node coordinates aligned from two nodes without need to use a temporary node technique.
A function type:
Input1: two nodes N1 and N2 ( For Vector Definition)
Input2: Node N3 ( To be projected perpendicularly to N1 and N2 vector )
output: Aligned N3 (New Coordinate ==> X,Y and Z )
Thanks in Advance,
Felipe

Hi Tinh,
I really appreciated your code, but unfortunately HM could not found the ::math::linearalgebra package. It is possible be installed our use an similar hypermesh library?
Thanks,
Felipe
Hi Tinh,
I found a similar functions in hypermesh:
::hwat::math::VectorCrossProduct {vector1} {vector2}
::hwat::math::VectorNormalize {valuelist} normvalue
It solved now.
Thanks very much!

Even if there is no available function, you can write them easily. Google for their formula.
An example expanse usage of expr command to do vector operations:
<?xml version="1.0" encoding="UTF-8"?>
I want to get the coordinates of a node and use it in defining the base point (while projecting). Can you please tell me how to do this?
Try
set coords [ join [hm_nodevalue $nid]]
Hi
I don't remember transforming matrix. But use vectors to find V04:
(N4 is projected of N3)
<?xml version="1.0" encoding="UTF-8"?>
From V13 you can utilize built-in package math::linearalgebra
<?xml version="1.0" encoding="UTF-8"?>
