Default baffles in openfoam extend

Hi there,

I was trying to solve the problem of using solidDisplacementFoam in OpenFOAM 2.2 to create a Penny Shaped Fracture. I was able to do that by using an STL file of a circular surface and using SHM to apply opposite forces on the two faces of the surface to create a fracture.

Now I have moved on to OpenFOAM extend 1.6 to make use of the solidMechanics applications available there to expand my work. I am facing difficulty in reproducing the penny shaped fracture case there. It gives me an error saying that

keyword level is undefined in dictionary "/home/ripu/OpenFOAM/OpenFOAM-1.6-ext/tutorials/solidMechanics/elasticSolidFoam/Penny/system/snappyHexMeshDict::castellatedMeshControls::featur es"

file: /home/ripu/OpenFOAM/OpenFOAM-1.6-ext/tutorials/solidMechanics/elasticSolidFoam/Penny/system/snappyHexMeshDict::castellatedMeshControls::featur es from line 46 to line 47.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 396.

FOAM exiting

I realize that this is because of the incapability of SHM to handle feature edge handling in OF1.6-extend. Is there any other way of doing this?

First hint:

- in your error message it seems that you wrote a word wrong:
keyword level is undefined in dictionary "/home/ripu/OpenFOAM/OpenFOAM-1.6-ext/tutorials/solidMechanics/elasticSolidFoam/Penny/system/snappyHexMeshDict::castellatedMeshControls::featur es"
keyword level is undefined in dictionary "/home/ripu/OpenFOAM/OpenFOAM-1.6-ext/tutorials/solidMechanics/elasticSolidFoam/Penny/system/snappyHexMeshDict::castellatedMeshControls::featur_es"
Second hint:

- you switched to OF-1.6-ext but I think you have already the 2.2 Version on your Computer. Therefor you can mesh in 2.2. and then use the mesh to use it on 1.6-ext for your solid mechanic solvers.

- That give you the ability to use the Advantage of sHM in 2.2. and the solvers of 1.6-ext


- it is a Long time ago that I used the extend Version because at the Moment I can do everything with 2.2.x. Therefor I do not know how good the snappyHexMesh Version works in the extend Version.

I thought that the extend Version will be released last year (OpenFOAM-2.0-ext) ... hmmm but still nothing happend.

Thank you very much for your reply Tobias. For now I have moved back to OpenFOAM 2.2.2 to take care of the task at hand. I will look into this in detail when I really need to. Your idea about using 2.2.x for SHM and 1.6-ext for solver is enticing.

Thanks again.
