Oper

Operation to perform:

SCALE

 — 

Interpolate TB-based material parameters in the linear or natural log scale.

ALGO

 — 

Set the interpolation algorithm to use for the subtable (or table if the material data table has only one subtable) being defined.

DEFA

 — 

Set the default value of the user-defined field variable used for interpolation (if no value was specified).

BNDS

 — 

Set the maximum and minimum bounds for individual field variables.

NORM

 — 

Scale the field variables before interpolation.

CACH

 — 

Enable/disable caching of interpolated data for performance.

Interpolation Parameters for Oper = SCALE

Par1

Independent variable, which can be any field variable specified via the TBFIELD command.

Par2

Index of any material parameter specified via the TBDATA command.

Par3

Scale to use for the independent variable. Valid options are LINEAR (linear) or LOG (logarithmic).

Par4

Scale to use for the dependent variable (the material parameter specified via Par2). Valid options are LINEAR (linear) or LOG (logarithmic).

Interpolation Parameters for Oper = ALGO

Par1

Interpolation algorithm:

LINEAR – Linear 1-D / 2-D (default).
LMUL – Linear-multivariate interpolation (multidimensional).
RBAS – Radial-basis interpolation (multidimensional).
NNEI – Nearest-neighbor (multidimensional).

Par1 = LINEAR is available for all material models. The remaining options are limited to a subset of material models. For more information, see Material Model Support for Interpolation in the Mechanical APDL Material Reference.

Interpolation Parameters for Oper = DEFA

Par1

The field variable on which the operation is being applied.

Par2

Default value of the field variable for which an initial value was not specified.

Interpolation Parameters for Oper = BNDS

Par1

The field variable on which the operation is being applied.

Par2

Lower bound of the field variable.

Par3

Upper bound of the field variable.

Interpolation Parameters for Oper = NORM

Par1

Reserved for future use.

Par2

Enable/disable field-variable normalization for interpolation.

OFF – Disable (default).
ON – Enable.

Interpolation Parameters for Oper = CACH

Par1

Reserved for future use.

Par2

Enable/disable caching of interpolated material parameters for performance.

OFF – Disable (default).
ON – Enable.

Notes

For a list of the supported material data tables (TB), see Logarithmic Interpolation and Scaling in the Mechanical APDL Material Reference.

Oper = DEFA, BNDS, NORM and CACH are supported for the linear multivariate (TBIN,ALGO,LMUL) and nearest-neighbor (TBIN,ALGO,NNEI) interpolation algorithms only.
