loss of dimensions during integration...
Hi!
I have a little problem during an integration. I have 2 volScalarField (T and phase_gamma) and a dimensionedScalar (V_gamma). the dimensions are the following : T [1 3 1 0 0 0 0] phase_gamma [0 0 0 0 0 0 0] V_gamma [0 3 0 0 0 0 0] during my process, I need to reassign T according to : T = phase_gamma*INTEGRAL(phase_gamma*T,V_gamma)/V_gamma I use the following code: T=phase_gamma*sum(fvc::volumeIntegrale(phase_gamma *T))/V_gamma The compilations is ok. However I obtain an error during the execution of the code ("different dimensions"). It looks as if the operation "sum(fvc::volumeIntegrale(phase_gamma*T))" do not account for the dimension. Do you have any idea ? Thank you for your help, Cyprien 
Hi Cyprien,
I think "sum" is not taking dimensions into account. Try fvc::domainIntegrate("field") instead of sum(fvc::volumeIntegrale("field")). Regards, Stefan 
It works !! thank you very much !

Hi,
I'm a beginner with openfoam and I need to integrate a pressure by a length (r_1). I've tried plenty of things but it doesn't work. I ended up with this : scalar pression1= ((gamma1*gamma1)/(4*pi*pi))*fvc::r_1integrate((1::exp((r_1*r_1)/(r_eq1*r_eq1)))*(1::exp((r_1*r_1)/(r_eq1*r_eq1)))/(r_1*r_1*r_1)); could you please tell me what is wrong. Otherwise I also wanted to write directly the integral but unfortunately I need to use the exponential integral (Ei)function and I don't know how to implement it in my program. Don't you have any idea how to use it? Thank you in advance, Ingrid
