Coupling 3D and 1D Skeletal Muscle Models

Coupling 1D Beams to 3D Bodies

A new technique for coupling one dimensional beam elements to three dimensional bodies is described. The essence of the problem is to ensure compatibility of the displacements at the interface. This is achieved by equating the work done at the dimensional interface by the 3D nodes with the work done at the 1D node. This is carried out in a manner similar to that used in the development of Reiss...

Ansys Cfd Coupling to 1d Codes Amesim & Gt-power and Examples of 1d-3d Coupling Ansys Cfd Coupling to 1d Codes Amesim & Gt- Power and Examples of 1d-3d Coupling

For the ANSYS CFD codes CFX and Fluent coupling links to several 1D codes exist allowing for a wide range of multi-physics applications. As an example, a flexible coupling infrastructure in terms of supported multiphysics coupling conditions between ANSYS CFX and LMS AMESim is outlined. Examples of the wide range of coupling solutions of ANSYS CFD (CFX and Fluent) and coupled 1D-3D applications...

Electromechanical Coupling between Skeletal and Cardiac Muscle

Skeletal myoblasts form grafts of mature muscle in injured hearts, and these grafts contract when exogenously stimulated. It is not known, however, whether cardiac muscle can form electromechanical junctions with skeletal muscle and induce its synchronous contraction. Here, we report that undifferentiated rat skeletal myoblasts expressed N-cadherin and connexin43, major adhesion and gap junctio...

Excitation-contraction coupling in skeletal muscle.

Electrical models of excitation-contraction coupling and charge movement in skeletal muscle

The consequences of ionic current flow from the T system to the sarcoplasmic reticulum (SR) of skeletal muscle are examined. The Appendix analyzes a simple model in which the conductance gx, linking T system and SR, is in series with a parallel resistor and capacitor having fixed values. The conductance gx is supposed to increase rapidly with depolarization and to decrease slowly with repolariz...
