Go to the root folder containing setup.py and run the following in terminal. Install the repository in editable mode for development. If you want to use this tool with your Docker image then please install all the different libraries mentioned in the above repository. Unfortunately the built in Fenics mesh generator is not any good for periodic boundary conditions (doesnt enforce identical mesh elements at the boundaries). This Docker image has all the correct version of libraries required for this tool. This repository is tested with the Docker image provided here. These files can be visualised in Paraview for validating the correctness of the marked subdomain. The problem is that when dealing with large meshes I couldnt work with the xml data format any more. ![]() sub_domains - This folder will contain the XDMF files of different subdomains marked.mesh - This folder will contain the data that we will use in the script i.e, the XDMF files for different entities of mesh and the JSON file containing the corresponding tag names and tag values.If adaptivity is necessary one alternative is to remesh during computations. Run the following in the directory which contains the. ReMSH-Gmsh To the best of my knowledge adaptivity (coarsening in particular) is not a strength of FEniCS. You can install this with the following commands: sudo -H pip install meshx Once you are comfortable with FEniCS and Gmsh, you can create your own demos by following the steps below. It has all the correct version of different libraries that are supported by this tool. To use this tool you have to use the docker image provided here. This work is derived from the work done during my GSoC project and is based on the following snippet of code made by Michal Habera. How to create a constant boundary conditions using a geometrical identifier. A simple tool to convert mesh created from Gmsh to XDMF for use in FEniCS. Create a simple mesh using the GMSH Python API and load it into DOLFINx.
