  What does the following error message indicate?: n*** ERROR *** CP = 0.469 TIME= 13:33:17 nInsufficient information. Unable to initialize material interpolation algorithm. Linear multivariate interpolation requires the parameter space to be fully spanned with at least n+1 supporting points. Please refer to the documentation of the General Interpolation Library, ANSYS Composite PrepPost User's Guide, chapter 5.5. n

  Hi Array,nnThis error message appears to be with respect to composite prep-post and it would seem that there are not enough data points to successfully interpolate mu between all the values given. According to the TBFEILD doc, no limit exists on the number of values that one can specify. Also, Section 5.5.1.2. of Composite Prep/Post offers an explanation of the Linear Multivariate Interpolation scheme that is referred to in the error message together with the interpolation formulas.nnRegards,nAshish Khemkan
