Typical Maxwell 2D/3D Results

Optimetrics

What is Optimetrics ?Optimetrics enables engineers to determine the best design variation among a model's possible variations.

Create the original model, the nominal design, and then define design parameters that vary

Optimetrics includes five unique capabilities: 1. Parametrics: Define one or more variable sweep definitions, each specifying a series of variable

values within a range. Easily view and compare the results using plot or table to determine how each design variation affects the performance of the design.

2. Optimization: Identify the cost function and the optimization goal. Optimetrics automatically changes the design parameter(s) to meet the goal. The cost function can be based on any solution quantity that can be computes, such as field values, R,L,C force, torque, volume or weight.

3. Sensitivity: Determine the sensitivity of the design to small changes in variables in the vicinity of a design point. Outputs include: Regression value at the current variable value, First derivative of the regression, Second derivative of the regression

4. Tuning: Variable values are changed interactively and the performance of the design is monitored. Useful after performing an optimization in which Optimetrics has determined an optimal variable value, and you want to fine tune the value to see how the design results are affected.

5. Statistical: shows the distribution (Histogram) of a design output like force, torque or loss caused by a statistical variation (Monte Carlo) of input variables.
