Dimension Problem in If Condition
Hi Foamers,
I would like to implement a new cavitation solver in openFoam! I added a transport equation for mass fraction where I need to compare my local pressure (p) with a scalar experimental value pEq!
During the compiling of the code I got a dimension error!
Can anyone help me to fix it?
Here is the transport equation code:
Quote:
// Solve Mass Fraction Equation for the Gas Air (undissolved)
{
#include "sourceTerms.H"
//Scalar Transport Equation for Mass Fraction
if (pEq > p) //p)
{
fvScalarMatrix f4Eqn
(
fvm::ddt(rho, f4)
+ fvm::div(rhoPhi /*phi*/, f4)
- fvm::laplacian(Gamma4,f4)
//+ fvm::Sp(AaL,f4)
+ fvm::Sp(AdL,f4)
);
f4Eqn.relax();
solve( f4Eqn /*== AaL*fGlim*/);
}
else
{
fvScalarMatrix f4Eqn
(
fvm::ddt(rho, f4)
+ fvm::div(rhoPhi /*phi*/, f4)
- fvm::laplacian(Gamma4,f4)
+ fvm::Sp(AaL,f4)
//+ fvm::Sp(AdL,f4)
);
f4Eqn.relax();
solve( f4Eqn == AaL*fGlim);
}
//Update of All Phases Coeffcients
//rho == scalar(1)/((f1+f4)/rho1 + f2/rho2 + f3/rho3);
//rhoPhi == rho*phi;
}

Here the declarations for pEq and p
