Reynolds number
 
Hi, is there any simple way of determining the Reynolds number, or any non-dimensional number for that matter, at a point in a flow using ANSYS Workbench 13?

Local RE Number
 
Create a custom field function: Define it as "density * velocity-magnitude / viscosity"

Then obtain the value at a point using a point-monitor.

The reynolds number at that point is equal to the value of the custom field function TIMES a length scale.

Make sure your length scale makes sense.
