What it does
- API
- PetIBM installs a library and header files for building flow solvers, with API documentation and simplified example solvers provided.checked 9 Oct 2026
- Assessment tools
- Nochecked 24 Sep 2026
- Audience
- The project provides end-user installation instructions and separate guidance for developers extending or debugging PetIBM.checked 9 Oct 2026
- Authoring tools
- Nochecked 24 Sep 2026
- Bodies and meshes
- It supports multiple immersed bodies, prescribed motion, and 2D and 3D stretched Cartesian meshes.checked 9 Oct 2026
- Compatibility limit
- The CMake instructions for finding PetIBM dependencies exclude MPI, which must be found separately.checked 9 Oct 2026
- CPU and GPU solvers
- Linear systems can be solved on CPUs with PETSc KSP objects or on multiple CUDA-capable GPUs using NVIDIA AmgX, connected through AmgXWrapper.checked 9 Oct 2026
- Delivery mode
- desktopchecked 24 Sep 2026
- Dependencies
- Building from source requires a GNU C++ compiler, PETSc with parallel HDF5, an MPI implementation, yaml-cpp, and SymEngine; AmgX and AmgXWrapper are optional for GPU linear solvers.checked 9 Oct 2026
- Installation
- End users can install prebuilt GPU-enabled packages with Anaconda or use Docker and Singularity/Apptainer containers.checked 9 Oct 2026
