Parametric analysis: examples
Example 1: a geometric parametrized analysis
We are interested in the influence of geometric dimensions of a magnetic circuit. The geometry of the studied device is described with geometric parameters.
A parametrized analysis of this type requires the following steps:

definition of a variable quantity: e.g., airgap

definition of the variation mode of this quantity: e.g., airgap values of 0.7, 0.9, 1.1, and 1.3 mm

successive solving processes to obtain: the 4 solutions for the 4 values of the airgap

results analysis on the 4 computed solutions: e.g., force on a piece as function of the airgap value, etc.
Example 2: a physical parameterized analysis
We are interested in the influence of magnetic properties of the material of a magnetic circuit. The material is characterized by a B(H) curve, defined by two values, the initial relative permeability μ_{r} and the saturated magnetization J_{S}.
A varying analysis of this type presumes the following steps:

definition of a variable quantity: e.g., the initial relative permeability μ_{r}

definition of the variation mode of this quantity: e.g., values 100, 1000 and 4000 of μ_{r}

successive solving processes to obtain: the 3 solutions for the 3 values of μ_{r}

results analysis on the 3 computed solutions: e.g., force on a piece as function of the μ_{r} value, etc.
Example 3: time dependent study
We are interested in the force acting on the mobile part of a contactor after supplying the coil.
A varying analysis of this type presumes the following steps:

definition of the time dependence of the current in the coil: function i(t)
The current form is defined with a step type function i(t):

i(t) = 0, for t < 0.02 s

i(t) = 25 A, for t > 0.02 s


definition of the variation mode of the time variable, e.g., number of time steps and value of the time interval

successive solving processes to obtain the set of solutions corresponding to the defined time steps

results analysis on the set of computed solutions, e.g., force on a piece as function of time, etc.
