August 20, 2006, 18:08	Is it possible to take the Lag	#1
coops Member Shaun Cooper Join Date: Mar 2009 Posts: 54 Rep Power: 17	Is it possible to take the Lagrangian derivative of a volVectorField (U) and (in a seperate equation) also a volScalar Field (T)? At the moment when I try to use these I get the following errors: fvc::DDt(U) + .... error: no matching function for call to 'DDt(Foam::volVectorField&)' and for T: fvc::DDt(T)+.... error: no matching function for call to 'DDt(Foam::volScalarField&)' If it is not possible can anyone suggest a solution? Thanks in advance, Shaun
