Error ASE change material

I get the following error for an anisotropic material


Could you please upload your defective SSD project? I can not recreate the error message with the latest SOFiSTiK Version 2022.
Otherwise check the mentioned TEDDY Example.

thanks, I upload my defective SSD

As described within the error message, the factor

1 - muexy mueyx = 1 - muexy muexy E/E90 = 1-0,330,33157,9/9,584 = -0,794

gets negative. Please increase the anisotropic E-Modul (E90). The reason for this behaviour is described within the AQUA manual.

And you should read the comments in the mentioned TEDDY example.
