[Adeleine Cabrera]

Can anyone please help me fix the error above. I inserted a command for the structural analysis. I'm trying to input a non-linear stress-strain for different temperatures (2,100,200,300,...degrees celcius).

Hi Adeleine

TBPT defines XY data points for some material models defined by the TB command...which there are none in the APDL code shown.  Not all material models defined with TB use the TBPT command.  Looks like material with ID number 5 in the model is one of those.
