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.

Start Continuity

  • Launch the Continuity 6.4 Client
  • Click OK to bring up the main window

Load Geometry

  • File→Library→Search...
  • Find the model named dog_geom

  • Right click on the model and select Load

  • Select Reset (without save) then proceed; the second option.

Render Elements

Load Dynamic Model

  • File→Library→Search...
  • Find the model named BM_Hilltype_sympy

  • Right click on the model and select Load

  • Select Retain current problem, but overwrite the following objects:...; the third option.

Load Constitutive Model

  • File→Library→Search...
  • Find the model named Ogden_Holzapfel_2009_U8_active_hilltype

  • Right click on the model and select Load

  • Select Retain current problem, but overwrite the following objects:...; the third option.

Solve Nonlinear

  • File→Send

    • If the Dimensions Form appears, simply click Apply Marked Recommendations and then OK

  • Mesh→Calculate Mesh...

  • Biomechanics→Solve Nonlinear...

    • 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.
