663    MATERIALS : a temperature (xxx °C) is less than the min usage temp... warning message


Question: 

What exactly does this Warning message mean:

Example:

663    MATERIALS : a temperature (-15 °C) is less than the minimum usage temperature (-6.7 °C) of SA387GR22CL2 ASME II.

 

Answer: 

Generate a complete output report of the calculations and search for the reported value (ex. -15 °C). Review each occurrence of the value looking for relevant information.

Example: 

Design MDMT

Next, go back to the model to confirm the setting.

Example:

Finally confirm the library data on this material selection.

Note: Temp Usage Min = 20 Units system = US, Temp = 20°F or -6.7°C 

Conclusion:

This notification serves to inform the user that the temperature specified in the model (ex. -15°C ) surpasses the limits of the chosen material (ex. 20°F or -6.7°C ). To eliminate this warning, consider the following options:

1. Select a different material that meets the requirements of your design.

2. Revise the material library with suitable values derived from testing conducted by a credible source.
