Adaptive Method

The Adaptive Method node computes a vector field adapted to the shape of the geometry so that the streamline density is constant on cross sections of the geometry. When the Normalize vector field check box is not selected in the Curvilinear Coordinates node, the method also ensures conservation of the vector field, meaning that the magnitude of the field will vary as a function of the cross-section area of the domain.

This method is similar to the Coil Geometry Analysis approach used in the Multi-Turn Coil feature in Magnetic Fields (in the AC/DC Module).

To define the equation in the geometry, you can add the following boundary conditions:

•

Inlet

•	Interior Wall

•

Jump

•

Outlet

If the vector field must enter and exit the domain selection, add an Inlet and one or more Outlet subnodes and select respectively the inlet and outlet boundaries for the vector field. If the vector field is entirely contained in the domain selection, add a Jump subnode and select an interior boundary where the vector field must be orthogonal. Only one active Inlet or Jump subnode is allowed. Use the Interior Wall subnode to further shape the path of the vector field.
