Generating 3-D axisymmetric mesh using extrudeMesh
I am modelling an axisymmetric jet and would like to use extrudeMesh to convert a 2-D mesh into 3-D. I created a 2-D mesh in Fluent then used fluentMeshToFoam to convert it. I would now like to revolve this 2-D mesh 45 degrees about a symmetry axis, effectively making a 1/8th section.
The problem is I can't get extrudeMesh to work. It comes up with the following message:
--> FOAM FATAL IO ERROR:
cannot open file
file: /home/hugh/OpenFOAM/hugh-2.1.0/3d/jet_3d_extrude/system/extrudeMeshDict at line 0.
From function regIOobject::readStream()
in file db/regIOobject/regIOobjectRead.C at line 87.
I have looked at other threads and they say to run extrudeMesh from a separate directory to that which your 2-D mesh is stored and then call the 2-D directory in your extrudeMeshDict. I have done this but it still doesn't work. Could someone please help me!
It looks like it can't find or open your extrudeMeshDict at all. What directory are you executing extrudeMesh from?
If your extrudeMeshDict is located at:
then you should be able to run extrudeMesh from
Otherwise you might have file ownership properties. Maybe try
chmod 700 extrudeMeshDict
