Parallel simulation of variably saturated flow with adaptive mesh refinement (D08)

• Subject Area: Mathematics ; Hydrogeology, Hydrology, Limnology, Urban Water Management, Water Chemistry, Integrated Water Resources Management
• Term: from 2013 to 2018
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 15232683

The accurate numerical simulation of 3D subsurface flow can be accelerated tremendously if the highest resolution is not used uniformly throughout the domain, but adaptively in regions that feature strong variability. We will extend the new parallel prototype code for adaptive mixed finite elements with a preconditioned nonlinear solve and for the time-dependent case. New parallel algorithms for parallel adaptive mesh refinement will then be coupled to the subsurface component of TerrSysMP ParFlow.
