I used user defined materials for stress analysis. An error came up as below:
99E Expansion Coefficients for user defined materilas must be set by the user.
I do not know where / how to input it.
Thanks,

Done.
Thanks

I am also having this problem. Would you mind explaining how you fixed it? Thanks

Just put the expansion coefficient into the temperature field, instead of the temperature. Check the "help text" here, it explains what to do and what the expected "units" are.

Where can I find "help text here" ?
