domc New Member Join Date: Jul 2019 Posts: 1 Rep Power: 0	Hi, I am trying to rotate a aerofoil using overset mesh. Currently I have managed to translate the aerofoil using the motions and translation tools. For the rotation the rotation is defined as rotation rate but I am wanting to only rotate by 20degrees. My question is how do I set up a incremental rotation in star ccm+. I have tried creating a field function and put the definition as [0,0,sin($Time)] but get the error "Expression does not evaluate to double: [0,0,sin($Time)]". Any help will be much appreciated. Thanks
