Seminar 09 March

This weeks seminar, at 1pm in the “delta” room, will be given by Ivar Stefansson, who will present his master thesis.

Title: A comparison of two numerical methods for flow in fractured porous media and the impact of intersection cell removal

Abstract: A very brief description of a cell-centered finite volume method and a mixed finite element (mortar)  method will be followed by the comparison of the two methods. I will use the opportunity to mention and summarize
the benchmark study led by Bernd Flemisch. This part will be followed by an presentation of a procedure for   eliminating small discretization cells at the fracture intersections aimed at improving condition numbers and time step restrictions for flow and transport problems.
