sundials-sandbox

Template repository for codes that utilize SUNDIALS.

This includes simple implementations of customized N_Vector and SUNLinearSolver modules, along with testing routines for each. It also includes five SUNDIALS examples, to serve as templates for codes that utilize the ARKODE and CVODE integrators from SUNDIALS:

• N_Vector module: nvector_serialcomplex.h and nvector_serialcomplex.c, with testing routine testComplexNVector.c.

• SUNLinearSolver modules: sunlinsol_sptfqmrcomplex.h and sunlinsol_sptfqmrcomplex.c, with testing routine test_SPTFQRM.c, sunlinsol_pcgcomplex.h and sunlinsol_pcgcomplex.c, with testing routine test_PCG.c

This repository provides a simple CMakeLists.txt file to compile each of the above codes against a given SUNDIALS installation.

This setup assumes out-of-source builds, and requires that the path for the installed SUNDIALSConfig.cmake file be held in the CMake variable SUNDIALS_DIR. For example, from within this directory:

mkdir build
cd build
cmake -DSUNDIALS_DIR=/usr/local/sundials/lib/cmake/sundials ..
make

This has been tested using SUNDIALS v7.1.0. Older SUNDIALS installations may be used by changing to a different branch:

• main: designed to work with SUNDIALS v7.1.0 (should work with any v > v7.1.x)
