Q. In viscoelastic curve fitting routine, when user reads in bulk relaxation data only, curve fitter fails to produce a curve and generate coefficients correctly.
When he adds same data for both shear and bulk relaxation, curve fitting is successful. What is wrong?
A. This was a bug in ANSYS 9.0 and 10.0. At 9.0 the curve fitter fails completely. At 10.0, it is worse because the curve fitter generates a curve, calculates the coefficients, but then saves the coefficents incorrectly with the TB command. (Refer to Defect 33341). This has been corrected at 11.0beta. This is not a class 3 error at 10.0 because it is identified in errata report.
