- The Poisson's ratio, v.
- Temperature, if the data depend on temperature.
- Value of the first field variable, if the data depend on field variables.
- Value of the second field variable.
- Etc.
- If *type*=SHEAR, the table data specify the following:
- The shear modulus,G.
- Temperature, if the data depend on temperature.
- Value of the first field variable, if the data depend on field variables.
