tsai-hill criterion - implement a formula in ansys

[Dmaz]

Hello everyone after doing an analysis on a laminate in composite material with classic ansys I should make the plot of factor fth provided by the resistance criterion of tsai-hill. the formula is the one reported in the image and the terms of this coefficient I know practically everything: voltages present as analysis results and limit voltages inserted as parameters or as failure criteria data.
how can I create an element table of the coefficient fth so you can then make a plot?
Thank you all!

I should have solved this way, making the term fth plot found:
