Hi.
studyhardhardhard:
Issue 1: In the following code, my PyCharm IDE underlines self, x, on_boundary with a squiggly line and gives a warning that the signature of the method ‘InnerBoundary.inside()’ does not match the signature of the base method in class ‘SubDomain’. I want to find the usage of the base method inside, but PyCharm indicates that it cannot find usage in the project files. Nevertheless, the code runs without errors. As a beginner, I am deeply troubled by this.
This warning is triggered by static code analysis tools to let you know that there might be an issue, as the original dispatch method has a different signature and because SubDomain is using *args and **kwargs internally. This doesn’t necessarily indicate an error, as you saw. You can ignore that warning.

Issue 2: I am facing serious compatibility issues with my mshr installation. In my version of fenics-dolfin 2019.2.0.dev0, it seems incompatible with mshr version 2019.1.0, resulting in the error ImportError: libboost_filesystem.so.1.82.0: cannot open shared object file: No such file or directory. My versions of boost-cpp and libboost are 1.84.0, and installing a lower version of boost is not feasible, as fenics-dolfin 2019.2.0.dev0 requires libboost >=1.84.0,<1.85.0a0. If I use fenics version 2019.1.0 and install libboost version 1.78, mshr works, but then the MeshView function is not available.
Mshr has not been supported for quite some time, so its use is not recommended. Please use GMSH to generate the meshes. Meshio is pretty useful to import the meshes to FEniCS using the .xdmf format. There is a lot of posts dealing with that. For example: Transitioning from mesh.xml to mesh.xdmf, from dolfin-convert to meshio - #263 by Devin , Gmsh 4.4.1 in FEniCS? Meshio - #9 by SantiagoOrtiz , How to import xdmf mesh generated by gmsh into fenics - #10 by dokken , among others.
Cheers.
