#### 5.5.1.3. Known Limitations

The linear multivariate interpolation algorithm requires the parameter space to be fully spanned. In particular, this restriction requires that none of the specified material fields are constant, as illustrated in the figure below.

Note that in Engineering Data, temperature is often provided by default as a potential material field. If you do not want to include temperature-dependence in your analysis, remove it in Engineering Data from the Table of Properties by clicking the drop-down icon next to the Temperature field, and selecting Delete.
