TDycore is a set of dynamical cores for simulating three-dimensional land processes in order to address questions about the hydrological cycle at a global scale. TDycore applies higher-order, spatially-adaptive algorithms on geometries that capture features of interest to study the subsurface transport of water and energy.

TDycores provides two dynamical cores:

  • a finite element (FE) version based on an H-div conforming space

  • a finite volume (FV) version based on the multi-point flux approximation (MPFA)

Both dycores can use meshes with hexahedral or triangular prismatic cells with planar faces. The prismatic cells are aligned logically along a z axis.
