Solves neutron transport and heat conduction equations using meshless methods

ibex

The ibex code implements meshless methods for the solution of the neutron transport equation and heat conduction equation. The discretization methods include the strong-form collocation method and the weak-form meshless-local Petrov-Galerkin (MLPG) method.

The code is hosted at https://github.com/brbass/ibex.

For the theory behind the code, see https://github.com/brbass/umich_dissertation.

ibex's Issues

CMake needs to be run twice

The flags for the C++ compiler are in the incorrect place in the base CMakeLists file, meaning the cmake command needs to be run twice to work correctly.

Add tests

The following is a continuously updated list of tests that need to be added.

• Test analytic integration in 1D and 3D in tst_Weight_Function.cc
• Simple two-group analytic cases
• Infinite medium test in 3D
• Finish comparing SUPG and standard operators in tst_Scattering_Equivalence
