Description
This tutorial will demonstrate how to build a biomechanics model of dog ventricles using different pre-built components. The Model consists of 4 components. The first component is the geometry with 48 tri-cubic elements. The second component is the dynamic (active tension) model. The third component is the constitutive model. The final component is the circulation model with the corresponding boundary conditions.

Specify the Number of Steps as 2
Specify when sum of solution increments < as 1e-002
Specify when sum of unconstrained residuals < as 1e-002
Click the Solve button, and wait for the solver to finish. While the solution is being computed the window will remain open. There will also be output listed to the console window and the Python shell.
