loss of dimensions during integration...
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:
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,
I think "sum" is not taking dimensions into account. Try fvc::domainIntegrate("field") instead of sum(fvc::volumeIntegrale("field")).
It works !! thank you very much !
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,
