Hi

http://openfoam-extend.svn.sourceforge.net/viewvc/openfoam-extend/trunk/Breeder_ 1.5/utilities/preProcessing/simpleViewer/

I am not able to open the above mentioned link , can somebody repost it again , I just want to see how it works .

with regards

But better than that and as Bernhard implied, starting with OpenFOAM 2.0.0 we can run paraFoam with an additional option:

Code:

paraFoam -block

In my experience calling

Code:

paraFoam -block

works only when there are no errors in the blockMeshDict.
However, if you mess it up, and blockMesh aborts and reports a topological error, paraFoam won't work either, because there is no mesh to read.

But, you can always read blockMeshDict with pyFoamDisplayBlockMesh.py to display all nodes, patches and cells.

This really speeds finding the error up.

In the picture below (sorry for the huge image), a topological error prevents blockMesh from creating a mesh. Viewing the output of pyFoamDisplayBlockMesh.py indicates the root of the error.

Hi
Gerhard .
Thanks for the reply .
I will try this one to visualize blockMesh .But my intention was to see the code , how simpleViewer is reading the blockMesh .with regards
