Elasticity Method
Add an Elasticity Method node to compute the vector field based on the solution with the eigenvalue closest to zero for the following eigenvalue problem:
The vector field v is the same as u but normalized if normalization is selected.
The Elasticity method requires that you use an eigenvalue study.
To define the equation in the geometry, you can add the following boundary conditions:
•
Wall (the default boundary condition)
•
Outlet
In addition, a default Inlet node is added because one inlet must be added for the geometry to define the positive direction of the vector field for the curvilinear coordinate as indicated by the arrow on the inlet boundary in the Graphics window.
