=== 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. ==== Send and Calculate Mesh ==== * [:Continuity/Documentation/Help/FileSend:File→Send] * If the Dimensions Form appears, simply click '''Apply Marked Recommendations''' and then '''OK''' * [:Continuity/Documentation/Help/MeshCalculateMesh:Mesh→Calculate Mesh...] ==== Render Elements ==== * [:Continuity/Documentation/Help/MeshRenderElements:Mesh→Render→Elements...] * Click the '''lines''' radio button * Click '''Render''' to display mesh lines === 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. === Load Circulation Model === * File→Library→Search... * Find the model named '''dog_lbbb_biomechanics_circulation''' * Right click on the model and select '''Load''' * Select '''Retain current problem, but overwrite the following objects:...'''; the __'''''third '''''__option. === Solve Nonlinear === * [:Continuity/Documentation/Help/FileSend:File→Send] * If the Dimensions Form appears, simply click '''Apply Marked Recommendations''' and then '''OK''' * [:Continuity/Documentation/Help/MeshCalculateMesh:Mesh→Calculate Mesh...] * [:Continuity/Documentation/Help/BiomechanicsSolveNonlinear: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.
