How to add a new module and program

This tutorial assumes that you have installed MoFEM with developer version using the script provided in Installation. And therefore, you probably have paths for the source code and the binary files (e.g. for release build type) of the Core Library and the Basic User Module as follows

  • Core Library
    • Source code: $HOME/mofem_install/mofem-cephas/
    • Binary files (build directory): $HOME/mofem_install/mofem-cephas/core-build-RelWithDebInfo-abcd1234
  • Basic User Module
    • Source code: $HOME/mofem_install/mofem-cephas/mofem/users_modules/
    • Binary files (build directory): $HOME/mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-abcd1234

How to add a new module

An existing module

To add a new MoFEM module that already developed, for example Solid Shell Module, you may wish to follow these steps

  • Locate Basic User Module source code
    cd $HOME/mofem_install/mofem-cephas/mofem/users_modules/
  • Clone Solid Shell Module
    git clone https://bitbucket.org/likask/mofem_um_solid_shell_prism_element.git
  • Compile codes for all modules
    cd $HOME/mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-abcd1234
    make -j4
  • By now you should see all the executables generated in the folder within um-build-RelWithDebInfo-abcd1234
    cd mofem_um_solid_shell_prism_element
  • Run the unit test (if the module has one)
    spack load cmake
    ctest

If you did every thing correctly, you should see the paths for MoFEM Solid Shell Module are as follows

  • MoFEM Solid Shell Module
    • Source code: $HOME/mofem_install/mofem-cephas/mofem/users_modules/mofem_um_solid_shell_prism_element
    • Binary files (build directory): $HOME/mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-abcd1234/mofem_um_solid_shell_prism_element

New module for your own purpose

The quickest way to create your own module is to replicate a module that already available in MoFEM and then replace the existing source codes with your own. For example, you can replicate MoFEM Solid Shell Module following general steps as follows

  • Clone the module to somewhere outside of MoFEM installation directory
  • Change file names and descriptions
  • Be careful with CMakeLists.txt, InstalledAddModule.cmake. Make sure all the names and paths are consistent with the new module name of your choice
  • Delete unnecessary source code files
  • Once everything done, create a new repository of your own on Github or Bitbucket
  • Upload your new files to the remote repository
  • Follow steps in the previous section to clone and setup your new module in MoFEM (How to add a new module - An existing module).

How to add a new program

The quickest way to add a new program to an existing module in your MoFEM installation directory is to replicate a program that already available in the same module of your choice. For example, you can replicate elasticity program in MoFEM Basic User Module following general steps as follows

  • Go to: $HOME/mofem_install/mofem-cephas/mofem/users_modules/basic_finite_elements/
  • Copy elasticity and paste it in the same place
  • Change file names and descriptions
  • Be careful with CMakeLists.txt. Make sure all the names and paths are consistent with the program name of your choice
  • Delete unnecessary source code files
  • Once everything done, compile source code by
    cd $HOME/mofem_install/mofem-cephas/mofem/users_modules/um-build-RelWithDebInfo-abcd1234/basic_finite_elements
    make -j4
  • You will see a new directory containing your new program
