FEM-shell

Features

• Structure solver build with libMesh FEM framework
• Parallelized with MPI
• Stand-alone and coupled version. Coupling achieved with preCICE (https://github.com/precice)
• Implements different types of flat shell element
• Efficient solving with PETSc support
• Applicable in multi-physics simulations, like fluid-structure interactions (FSI)
• Additional tool to generate meshes (meshGen)

Installation

First, compile PETSc. A description for the compilation of PETSc can be found here: http://www.mcs.anl.gov/petsc/documentation/installation.html

git clone -b maint https://bitbucket.org/petsc/petsc petsc
cd petsc
./configure
make all test

Second, compile libMesh. A description for the compilation of libMesh can be found here: http://libmesh.github.io/installation.html

git clone git://github.com/libMesh/libmesh.git
cd libmesh
./configure
make

Third, compile the two FEM-shell versions (and meshGen) by executing the corresponding SConstructs

cd src/meshgen
scons
cd ../fem-shell
scons
cd preCICE
scons

Requirements

gcc 4.8 or higher due to C++11 features.

Example runs

To test the program, several example problems are provided with the code. These tests can be run automatically be executing the two bash-scripts as follows:

cd src/fem-shell
./run_examples.sh
cd preCICE
./run_example.sh
