Description
Problem
Currently the active stress generated for the ChamberSphere block is not dependent on strain. Physiologically, the Frank-Starling mechanism allows the heart to generate more or less active stress in reaction to strain on the myocardium. Hence, this would be an important feature for our ChamberSphere block.
Solution
Add a strain dependent active stress model to the solver. Give the option to choose in the input file whether ChamberSphere uses a strain-dependent or -independent active stress model.

Research direction
Start by locating the ChamberSphere active-stress implementation in the solver and the input-file handling that selects its model. Define how strain-dependent and strain-independent behavior are selected, then verify that the solver uses the chosen model and that strain changes active stress as expected.
