How can I quantify the importance of a negative modal covariance diagonal value in a psd solution?

First use OUTPR,NSOL,1 to see the modal covariance table in the output. The contribution of a negative
quantity on the diagonal can be evaluated by reading the mode in POST1 with a factor equal to the square
root of the variance. The stresses obtained this way can be compared to the 1 sigma values for relevance.
