Sets parameters used for interpolation of
the material data
tables.
OperOperation to perform:
— | Interpolate TB-based material parameters in the linear or natural log scale. | |
— | Set the interpolation algorithm to use for the subtable (or table if the material data table has only one subtable) being defined. | |
— | Set the default value of the user-defined field variable used for interpolation (if no value was specified). | |
— | Set the maximum and minimum bounds for individual field variables. | |
— | Scale the field variables before interpolation. | |
— | Enable/disable caching of interpolated data for performance. |
Oper = SCALEPar1Independent variable, which can be any field variable specified via the TBFIELD command.
Par2Index of any material parameter specified via the TBDATA command.
Par3Scale to use for the independent variable. Valid options are LINEAR (linear) or LOG (logarithmic).
Par4Scale to use for the dependent variable (the material parameter specified via
Par2). Valid options are LINEAR (linear) or LOG (logarithmic).
Oper = ALGOPar1Interpolation 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.
Oper = DEFAPar1The field variable on which the operation is being applied.
Par2Default value of the field variable for which an initial value was not specified.
Oper = BNDSPar1The field variable on which the operation is being applied.
Par2Lower bound of the field variable.
Par3Upper bound of the field variable.
Oper = NORMPar1Reserved for future use.
Par2Enable/disable field-variable normalization for interpolation.
| OFF – Disable (default). |
| ON – Enable. |
Oper = CACHPar1Reserved for future use.
Par2Enable/disable caching of interpolated material parameters for performance.
| OFF – Disable (default). |
| ON – Enable. |
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.
