Hi there I am currently studying the heat transfer in a helical pipe and looking at the Nu is certain areas. However when trying to get values for the Nu at the wall I do not know how to get the monitor points exactly on the wall to read an accurate value.

Along with this I want to know the Nu within the fluid flow field, such as in the middle of the pipe. How would I be able to get this as the only options are for the surface Nu values.

Thank you in advance

Hello,

Assuming you know the equation of the Nusselt number, try creating a Custom Field Function (CFF) or an Expression. Then use this CFF or expression to determine the Nu at the required location.
