femo_alpha

A general framework for using Finite Element in PDE-constrained Multidisciplinary Optimization problems. It relies on FEniCSx to provide solutions and partial derivatives of the PDE residuals, and uses CSDL_alpha as the umbrella for coupling and mathematical modeling of the multidisciplinary optimization problem.

Installation

The minimal requirements to use femo_alpha for modeling and simulation are FEniCSx and CSDL_alpha. For modeling aircraft design applications, you may install CADDEE_alpha to enable coupling with solvers of other disciplines; for optimization, you will also need ModOpt on top of them for Python bindings of various state-of-the-art optimizers.

Installation instructions

It's recommended to use conda for installing the module and its dependencies.

• Create a conda environment for femo with a specific Python version (Python 3.9) that is compatible with all of the dependencies

  conda create -n femo python=3.9.10

  (Python 3.9.7 also works if Python 3.9.10 is unavailable in your conda)
• Activate the conda enviroment

  conda activate femo

• Install FEniCSx by conda-forge

  conda install -c conda-forge fenics-dolfinx=0.5.1

• Install CSDL_alpha and ModOpt by

  pip install git+https://github.com/LSDOlab/CSDL_alpha.git
  pip install git+https://github.com/LSDOlab/modopt.git

• Install femo_alpha as a user by

  pip install git+https://github.com/LSDOlab/femo_alpha.git

  or install femo_alpha as a developer by

  git clone https://github.com/LSDOlab/femo_alpha.git
  pip install -e ./femo_alpha
