Hello

I need to write (d-axialvelocity/d-radialcoordinate)^2.5 in the custom field function to extract the data. However, custom field function in FLUENT is not accepting a decimal number(2.5) in power and gives absurd results in the extracted data. However it gives correct results for a whole number. Can someone help me in this issue and provide me way to write 2.5 in power while writing a function in the custom field function.
Thanks in advance.

Try using pow 2 and sqrt.

Also check if the error is caused by neg numbers since ^2.5 would return imaginary numbers.
