fipy.meshes.factoryMeshes.CylindricalGrid1D(dr=None, nr=None, Lr=None, dx=1.0, nx=None, Lx=None, origin=(0,), overlap=2, communicator=DummyComm())

Create a 2D cylindrical mesh

Factory function to select between CylindricalUniformGrid1D and CylindricalNonUniformGrid1D. If Lr is specified the length of the domain is always Lr regardless of dr, unless dr is a list of spacings, in which case Lr will be the sum of dr.

Parameters:

  • dr (float) – Grid spacing in the radial direction. Alternative: dx.

  • nr (int) – Number of cells in the radial direction. Alternative: nx.

  • Lr (float) – Domain length in the radial direction. Alternative: Lx.

  • overlap (int) – the number of overlapping cells for parallel simulations. Generally 2 is adequate. Higher order equations or discretizations require more.

  • communicator (CommWrapper) – MPI communicator to use. Select serialComm to create a serial mesh when running in parallel; mostly used for test purposes. (default: parallelComm).
