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.
