Shiva

Shiva Discretization Library

Requirements: a C++20 compiler. CUDA builds require CUDA 12 or newer.

HIP consumers must explicitly require C++20 on each target that compiles HIP sources using Shiva. The Shiva interface propagates the C++ and CUDA standards; HIP standard propagation is unavailable at the project's minimum CMake version. Replace my_target with your consuming target:

set_target_properties(my_target PROPERTIES
  HIP_STANDARD 20
  HIP_STANDARD_REQUIRED ON)

Project Goals

The goals are:

• Provide portable device callable functionality to enable the application of discrete numerical methods such as the Finite Element Method, and Finite Difference Method, etc.
• Provide compile time interface to functionality through use of templates and constexpr for the special case where compile time knowledge is available.
• Specialize for common use cases to achieve maximum performance. For example a Hexahedral element with 1st order Lagrange shape functions and Gauss-Legendre quadrature.
• Support wide range of base geometries (tet, prism, pyramid, hex, polyhedral, etc), and discretization methods ( FEM, FVM, MPM, etc. )
