In this work we test the performance of different algorithms for the solution of a monolithic Fluid Structure Interaction (FSI) problem with a simplified ventricle model with the purpose to reduce the computational time. We study this challenging FSI problem by solving the fully coupled and the projection algorithm with a different number of penalty correction steps. The proposed FSI penalty projection algorithm is a modification of the Chorin method for fluids based on a predictor and a corrector step. The performance of the modified algorithm is tested by comparing the results obtained with the standard coupled algorithm with the ones obtained with the modified penalty projection scheme.

Abstract
In this work we test the performance of different algorithms for the solution of a monolithic Fluid Structure Interaction (FSI) problem with a simplified ventricle model with the purpose to reduce the computational time. We study this challenging FSI problem by solving the fully coupled and the projection algorithm with a different number of penalty correction steps. The proposed FSI penalty projection algorithm is a modification of the Chorin method for fluids based on a predictor and a corrector step. The performance of the modified algorithm is tested by comparing the results obtained with the standard coupled algorithm with the ones obtained with the modified penalty projection scheme.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
