I have specified User Materials for two materials and have entered the necessary values for temperatures up to 550 Deg C. The specified temperature of the elements is 543 Deg C. When I try and run i get the following error message:-

"On element 2560 to 2570 the TEMPERATURE for case is OUTSIDE the allowed range for this material. "

In my view the specified temperature of 543 Deg C is less than the 550 Deg C for which I have input values.

How do you check the input units for the temperature in the materials database?

Anybody know why I am getting the error message??

Do you see a thermal strain listed beside the entered temperature(s) for the input spreadsheet for element 2560-2570?

Yes.
When I entered the User material i made sure that the top temperature was above the max temperature specified in the element data. Plus the thermal strain was input.

I believe you will have to provide more hints if you wish assistance from this forum. I suggest you submit your query to SmartSuport. Or maybe post a small job that reflects your observations here.
