yurifrey New Member Yuri Frey Join Date: Jul 2013 Posts: 13 Rep Power: 13	Hello! I would like to set a porosity source with a power law like: Code: F = A u^(0.5) My problem is that openFoam seems unable to manage exponents < 1 (I get an error, while there are no problems if the exponent is > 1). Is there a solution? Thank you! Yuri
