Flux are available almost many places in Linear Actuator . in Which place's Flux can be used in FEM-Parameterized Linear Actuator block ?

in many inputs of FEM-Parameterized Linear Actuator need Flux Values,The flux input is asked.

For example,1)a matrix of the flux partial derivatives with respect to current.

2)matrix of the flux partial derivatives with respect to displacement.

3) matrix of the total flux linkage.
