Create helper function to create 1d mesh #159

Open greole opened 2 weeks ago

greole commented 2 weeks ago

for better testing we should also provide a function to create a 1d mesh which allows to insert number of cells along the 1d axis. With the following interface UnstructuredMesh create1DMesh(const Executor exec, size_t nCells); similiarly to https://github.com/exasim-project/NeoFOAM/blob/main/include/NeoFOAM/mesh/unstructured/unstructuredMesh.hpp and https://github.com/exasim-project/NeoFOAM/blob/main/src/mesh/unstructured/unstructuredMesh.cpp

What does nBoundaries in theunstructuredMeshactually mean? Is it the number of different boundary patches?

yes

In the BoundaryMesh class, what is the difference between the variables cn and sf?

greole commented 5 days ago

sf is what mesh.Sf() returns, ie the cell surface area vector (area and normal of faces) see https://www.openfoam.com/documentation/guides/v2006/api/classFoam_1_1fvMesh.html#a9dd61db5922c82527289434350fa0f17 and cn should be afaik the neighbour cell centres https://www.openfoam.com/documentation/guides/latest/api/classFoam_1_1fvPatch.html#a6644397238b36a49d0caf58d1d88e18d
