I am new to OpenFlower and just going through the examples. My setup is as follows:

Windows XP
gmsh v 2.4.2
OpenFlower v1.0 (msi installer)

I am trying to run the example NS_pipe_bend.flw. I ran into the error with "$NOD" - thanks for the fix. I was wondering how long before someone upgrade the mesh reader to gmsh 2.0?

I am now encountering the following error:

System composed of 1 Equations: eqn1
- Mesh file          : NS_pipe_bend.msh
Finished reading 3 frontiers.
       * Number of frontier faces: 796
       * Number of elements      : 0
Finding all faces in domain completed….
Assertion failed: m<nb-j, file src/Geometry/Octree.cpp, line 281

Please contact the application's support team for more information.

Any idea?
