This example uses the old approach to active tension modelling to simlate the active contraction and relaxation of two elements taken from the LV free wall of the RC heart model. In this simulation, the initial geometry is deformed purely by the generation of active tension within the cardiac tissue.
The level of activation is controlled via the ipacti file, which sets the level of activation to use for the current solution. This animation shows the results from the model when the activation level rises from zero to 1.5 and then returns to zero.
