I am getting the warning below about a material that is being evaluated outside of the defined temperature range; however, there are no specified temperatures, and both TREF and TUNIF were set to 550 (a temperature at which materials are defined). This warning is issued only if there is a 0 thickness (dropped) layer in the shell element. Is this a bug?
*** WARNING *** CP = 9.594 TIME= 09:53:16
Material property EX of material 1 of element 1 is evaluated at a
temperature of 0, which is below the supplied temperature range.
Temperature range checking terminates.
This was a code defect (#72923) that has been corrected for version 12.0. The erroneous warning message is no longer issued, and the temperatures are retained.
