I have following expression to define wall boundary temperature

110.84 [K]*log(t*1[s^-1]+1)+270.5 [K]

Fluent is able to plot it in expression editor window but I get following error:
======================
Error: Setup contains invalid expressions.
Refer to console for details.
Error Object: #f
=======================

Can someone help?

Thanks
