Hello,

In my model programed with python (TUI), i created a group of node. I would like  to  save  node numbers in array in order to export them (ascii format) to an another software. But i don't find functions (TUI) able  to make this operation.

Thank you in advance,
Arnaud

Hello Arnaud,
if you want to export all nodes from the mesh with the name "my_mesh":

***********************
mesh=my_mesh.GetMesh()
fil=open('model.nodes','w')   
for currentNode in range(mesh.NbNodes()):
    nodeCoords=mesh.GetNodeXYZ(currentNode+1)
    fil.write(('%d %14e %14e %14e\n') % (currentNode,nodeCoords[0],nodeCoords[1],nodeCoords[2]))
fil.close()
***********************
hope this will solve your problem
