CHECK TAPER
This function allows the user to check the taper for quadrilateral elements. Taper value is an amount of convergence. A perfect element such as a rectangle has a taper value of zero. The user can enter a value between 0 and 1 in the next dialog window (default is 0.5).
The user can include the failed elements in a new part.
The user can select any element to show its taper value in the PROMPT window.
