distance between two nodes

I realize that is not possible to get the distance between two nodes. So I am using a awk script to calculate that distance. But still is not a elegant solution. I want to calculate inside salome. But I am new in python. I am trying to access the node coordinates following the weida's script but in the python console when I write something like this import smesh pequeno=small.GetMesh() I got the following error Traceback (most recent call last): File "<input/>", line 1, in ? NameError: name 'small' is not defined. My mesh in the left window has the name small. So what is the problem? Thank you in advance.-
Hi, Paco.
You can write in the python console the following commands
import math
study = salome.myStudyManager.GetStudyByName("Study1"
theSObj = study.FindObject("small"
MObject = theSObj.GetObject()
node1=1
node2=48
coord1=MObject.GetNodeXYZ(node1)
coord2=MObject.GetNodeXYZ(node2)
distance=math.sqrt((coord1[0]-coord2[0])*(coord1[0]-coord2[0])+(coord1[1]-coord2[1])*(coord1[1]-coord2[1])+(coord1[2]-coord2[2])*(coord1[2]-coord2[2]))
print distanceSure "Study1", "small", 1, 48 can be replaced by any relevant values. Or write function to use these values as arguments if you plan to use it often.

Grigory
