tbin#

DataTables.tbin(oper='', par1='', par2='', par3='', par4='', **kwargs)#

Sets parameters used for interpolation of the material data tables.

Mechanical APDL Command: TBIN

Parameters:
operstr

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.

Notes

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

Command Specifications#

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.

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).
