Hello,

So I noticed a foam warning in Fe40 on both centos7 and ubuntu 18.04LTS whenever I try to deconpose a case.

To go into detail, this only happens when the decomposition method is chosen to hierarchical or patchedConstraints. I specifically tried the simpleFoam/motobike and MRFSimpleFoam/axialturbine_ggi tutorials. The log complains as followed:

Code:
--> FOAM Warning : From function decompositionMethod::loadExternalLibraries() in file decompositionMethod/decompositionMethod.C at line 508 Loading of decomposition library libparMetisDecomp.so unsuccesful. Some decomposition methods may not be available
--> FOAM Warning : From function decompositionMethod::loadExternalLibraries() in file decompositionMethod/decompositionMethod.C at line 508 Loading of decomposition library metisDecomp.so unsuccesful. Some decomposition methods may not be available
--> FOAM Warning : From function decompositionMethod::loadExternalLibraries() in file decompositionMethod/decompositionMethod.C at line 508 Loading of decomposition library scotchDecomp.so unsuccesful. Some decomposition methods may not be available
The thirdparty logs all show the packages installing successfully, so I don't know if this is a known bug?

Any help would be appreciated.

Edit: Definitely seems like for certain tutorials, it tries to load the decomp libraries twice, because even with warning, decomposition completed and the solution converges.

Thanks
