IGA-ADS

IGA-ADS is a Fortran framework designed to facilitate creating parallel numerical simulations for time-dependent PDEs using isogeometric finite element method.

Requirements

1. Dependencies

• BLAS
• LAPACK
• MPI

2. Tools

• compiler: reasonable Fortran2008 support is required (framework has been tested with ifort 14.0.2 and gfortran 4.8.5)
• build system: CMake 3.1 or higher

3. Compilation

To compile the code, create a directory for the build and execute following commands:

$ cmake ${PROJECT_DIR} $ make

where ${PROJECT_DIR} is the root directory of the project source. Options allow customizing which parts of the project are compiled. By default example applications are compiled.

• SKIP_PROBLEMS - if ON, the example problems are not compiled (default: OFF)
• COMPILE_TESTS - wether the unit tests are compiled. This should be disabled if pfUNIT is not available (default: OFF)

Options are specified as -Doption=value, e.g. $ cmake -DSKIP_PROBLEMS=ON ..
