Solving for Ports Only

For Driven solution types with ports.

To quickly compute only the 2D excitation field patterns, impedances, and propagation constants at each port:

• Under the General tab of the Solution Setup dialog box, select Solve Ports Only.

This disables the remaining settings for Maximum number of passes and Convergence per pass.

HFSS calculates the natural field patterns (or modes) that can exist inside a transmission structure with the same cross-section as the port. These 2D field patterns serve as boundary conditions for the full 3D problem.
