A meshless discretization method, based on the Meshless Local Petrov-Galerkin (MLPG) approach, is developed and implemented in parallel for the solution of axi-symmetric poroelastic problems. The performance of the resulting code is investigated on a realistic application concerning the prediction of land subsidence above a deep compacting reservoir. Nunerical results show that our approach is extremly scalable even on a very high number of processors (up 512) allowing solution of very large geomechanical problems.

Abstract
A meshless discretization method, based on the Meshless Local Petrov-Galerkin (MLPG) approach, is developed and implemented in parallel for the solution of axi-symmetric poroelastic problems. The performance of the resulting code is investigated on a realistic application concerning the prediction of land subsidence above a deep compacting reservoir. Nunerical results show that our approach is extremly scalable even on a very high number of processors (up 512) allowing solution of very large geomechanical problems.
