Hi, when I try to use the expression editor in wall thickness, the editor always tells me that Expression is not single-valued. I don't know what's wrong with it.

Appreciate everyone who replied.

It is a bug in earlier version of FLUENT, in 195 (19R3) and after, this issue has been fixed.

Just tested version 195 (2019R3) and the latest 2020R1, these functions are still not working. Although expression is available in thinwall thickness and shell conduction thickness input, they are not taken by the solver during calculation. This bug has been reported to FLUENT support, hopefully they can fix it next release.
