"We have developed an efficient numerical algorithm for the complex inter-reactions between solid and fluid"
PhD candidate Peiyao Luo (Numerical Analyses / Kees Oosterlee) is one of the winners of the 2017 Student Paper Competition at the Copper Mountain Conference on Multigrid Methods.
Peiyao: "I work on efficient multigrid methods for the interconnected Stokes-poro-elasticity-system. It can be applied for problems in the field of physics or geosciences. I have submitted my paper in last year's competition too, but it did not make the selection. "Now I am one of the winners because in this year we consider a more complicated model which has not been widely studied due to the complex coupling between the solid and fluid. Take the issues in Groningen with the earthquakes caused by the gas extraction. They insert water (liquid) in the ground (solid) to extract the gas. We have developed new mathematical algoritms for models to calulate the effects. These new models are faster and stronger."
