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.
