Preliminary monolithic fluid structure interaction model for ventricle contraction

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.
