TBIN

TBIN, Oper, Par1, Par2, Par3, Par4
Sets parameters used for interpolation of the material data tables.

Valid Products: Pro | Premium | Enterprise | PrepPost | Solver | AS add-on

Oper

Operation to perform:

ALGO

 — 

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

BNDS

 — 

Specifies the maximum and minimum bounds for individual field variables.

CACH

 — 

Enables or disables caching of interpolated data for better performance.

DEFA

 — 

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

EXTR

 — 

Controls extrapolation options.

NORM

 — 

Scales the field variables before interpolation.

SCALE

 — 

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

Interpolation Parameters for Oper = ALGO

Par1

Interpolation algorithm:

LINEAR – Linear 1D / 2D (default).
LMUL – Linear-multivariate interpolation (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 Material Reference.

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 = CACH

Par1

Reserved for future use.

Par2

Enable or disable caching of interpolated material parameters. Enable for better performance.

OFF – Disable (default).
ON – Enable.

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 = EXTR

Par1

Reserved for future use.

Par2

Set extrapolation/projection options for interpolating material parameters.

OFF / BBOX– Projects to the hyper-rectangular bounding box (default). An error occurs if query points exist outside the convex hull of points but inside the hyper-rectangular bounding box.
PHULL – Projects to the convex hull of points if a point is located outside the convex hull surface.

TBIN,EXTR is supported for the linear multivariate interpolation algorithm only.

Interpolation Parameters for Oper = NORM

Par1

Reserved for future use.

Par2

Enable or disables field-variable normalization for interpolation.

OFF – Disable.
ON – Enable (default).

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).

Notes

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

Oper = DEFA, BNDS, NORM and CACH are supported for the linear multivariate (TBIN,ALGO,LMUL) interpolation algorithm only.
