I have a cell register of density curvature that I'm trying to modify and create an expression with, as curvature_den*0.5.  However, I get the error "Function mul |d| b not found!" and the box is highlighted in red, indicating an error. Why is this happening and how do I fix it? Any mathematical operation I try to do with the cell register is causing this error, not just multiplication.

Hi,

The error message "Function mul |d| b not found!" suggests that there is an issue with the syntax used to create the expression involving the cell register in Ansys Fluent. 

In expression, Cell registers evaluate as boolean that is the reason of error. You can check user's guide for more details: 5.1. Introduction to Expressions (ansys.com)

Thank you.
