Hi all I am new in comsol... I have problema with a simple equation. I want write the equation:

                                                                                    (A/B)^(alfa),

alfa is constant less than 1. But I find following error?

--> Unit syntax error

Can somebody help me ?

Hi,

The "Unit syntax error" is a warning that the unit syntax in COMSOL Multiphysics cannot handle such an expression, which results in noninteger unit exponents. You can still use a variable defined using the expression above but only its numerical value. Perhaps your model is dimensionless? If you select None as the unit system, the warning about the unit syntax error disappears.

Best regards, Magnus Ringh, COMSOL
