Hello,

I have been struggling with the following error message in FEMLAB software: "The length of fem.appl(1).equ.ind must equal the number of domains in the geometry." I don't know exactly how to fix this error message. Would you please help me?

How can I find material properties of metallic glasses?

creep deformation

I am now going to model a sample with metallic glass (Cu-Zr-Ti) under stress and temperature loads.

Thank you very much!
