respected members of forum
i have perusing a problem regarding velocity in ansys fluent .there is an error as i mention below

my expression is 44[m/s]*(y/10[m/s])**0.133
error:Incorrect expression unit. Expression Unit [m s^-0.867], Required Unit [m s^-1]

i have lots of problem regarding this.please guide me about this

Change 10[m/s] to 10[m]. 10 might be value of velocity but the numbers do not care. [m s^-1] multiplied by [s^0.133] is leading to the incorrect units.
