This example provides pure mechanics and electromechanics examples on a slice biventricular geometry. The main use of this example is to test coupling of biventricular setups with a circulatory system.

Problem Setup

This problem generates a slice biventricular mesh using the carputils.mesh.BiVSlice class. The biventricular slice is tesselated into tetrahedra as shown below:

In all experiment types in this example, the top and bottom surfaces of the slice are constrained to lie in the same plane with Dirichlet boundary conditions, and an additional three nodes on the bottom ( $z=0$ ) surface are constrained such that free body rotation and translation is prevented. Two nodes on the x axis are prevented from moving in the y direction, and one node on the y axis is prevented from moving in the x direction:

Experiments

Several experiments are defined:

active-free - Run an active contraction simulation without constraints on cavity size or pressure
active-iso - Run an active contraction simulation with an isovolumetric cavity constraint
active-pv-loop - Run an active contraction stimulation with pressure/flux constraints imposed by Windkessel or circulatory models coupled to both RV and LV cavity. In this case both left and right ventricular cavities are coupled to a 3-element Windkessel model
