3-Tier Library Structure

System (global) level – predefined from Ansoft User Library – to be shared among several users at a company

(can be encrypted)

Personal libraries - to be used only by single user (can be

encrypted)



Advanced Analysis Features

Distributed Analysis – for computing farm toOptions for remote or distributed analysiscapability – can solve different rows of aparametric table on different PC’s (Tools >Options > Analysis)

Remote Solve – to solve on a single remotecomputer (must have separate license)

Optional convergence stopping criterion –use of % change of any output parameter (such as loss or torque) as an additionalconvergence stopping criterion, but does notimpact adaptive refinement

Optimetrics

What is Optimetrics ?



What is Optimetrics ?

¾ Optimetrics enables engineers to determine the best design variationamong a model's possible variations.

¾ Create the original model, the nominal design, and then define design

parameters that vary

¾ 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 changesthe 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.
