\ tissue scale\n
This tutorial elucidates the setting up of electro-mechanically\ \ coupled tisue simulations. As an example we use a simpliefied model of a left\ \ ventricular wedge preparation. For the sake of computational efficiency the apico-basal\ \ and circumferential dimension of the wedge are chosen by default to be small and\ \ the resolution of the model is coarse. As in the matching single cell stretcher\ \ experiment the same EP models (TT2, GPB) and stress models (TanhStress, LandStress,\ \ GPB-LandStress-model) are available which cover all three coupling modes (activation-time\ \ based ECC, weak calcium-driven ECC and strong calcium-driven ECC). The differences\ \ between coupling modes are illustrated in <code class=\"interpreted-text\" role=\"\ numref\">fig-ECC-physiology.
\n<h2 id=\"experimental-setup\">Experimental\ \ setup\n--length and --width\
\ input parameters. The wedge is mechanically fixated through homogeneous Dirichlet\
\ boundary conditions at the apical face of the wedge. At the anterior and posterior\
\ faces homogeneous Dirichlet boundary conditions are also applied, preventing any\
\ displacement in radial (z-axis) and circumferential (x-axis) direction, but allowing\
\ the wedge to slide along the apico-basal (y-axis) direction. Fiber rotation is\
\ set to standard values with -60 degrees at the epicardiacl face and +60 degrees\
\ at the endocardial face. The wedge is electrically stimulated epicardially at\
\ the center of the preparation.Input parameters\n
