You can create a user-defined approximation, which allows you to select the approximation technique and control all the options used by the technique. You can create user-defined approximations in the Design Gateway and the Runtime Gateway.
The following approximation techniques are available in Isight:
RBF Model
Response Surface Model
Kriging Model
Orthogonal Polynomial Model
Note:
These techniques are plug-ins that have been created by
SIMULIA and included with your Isight
installation. You can create your own approximation technique plug-ins
using the SDK Generator. For more information, see About Plug-Ins in the Isight Development Guide.
If you want to create an approximation automatically (where Isight
specifies many of these options for you), see Creating Approximations.
You can also create an approximation based on a previously saved coefficient
file. For more information on using a coefficient file, see Creating Approximations Using a Coefficient File.
To create a user-defined approximation, you first need to select the
technique and then configure each technique’s options. In addition,
you must also configure options that are relevant to all the techniques.
