I want to apply a specific profile for turbulence intensity, dependent on the distance from the ground (y), in the inlet boundary conditions, but here is an error:
my input for turbulence intensity profile: A*((y/B[m])^(-C))
and the error is: expression is not single-valued.
I would be delighted to have your advice on this.
Thanks in advanceJune 21, 2021 at 12:39 pmaitor.amatriainSubscriberIf C>0, then the expression is not single valued. You should add some kind real and/or absolute value operators, depending on the values of y, B and C (it is possible to have real/complex and positive/negative roots).
June 21, 2021 at 12:48 pmNimaNZSubscriberThank you Could you please give me an example of how I can fix this?
June 21, 2021 at 12:57 pmaitor.amatriainSubscriberI do not use expressions, but for UDFs, I would use functions as real() or fabsJune 21, 2021 at 2:38 pmNimaNZSubscriberThanks a million for your help
