In Ansys Fluent 14.5
How can I add new variable or expression such as "M=Force*distance" to do mathematical processes such as integration.

this can be done in ansys cfx14.5 easily. If you know how to use fluent, cfx is almost the same. you can try it.

in ansys cfx, you can find toolbar-'expression'. you just add the a variable or expression you need

In Fluent you use Custom field functions for this.

In the top menu "Define", then "Custom Field Functions".
