Re: About ConvectionBC

[steed188]

I tried the *uAv, but there seemed no difference ?

I First defined a global pointer uAv and initialize it.

Code:

T aveOut =0;
T * uAv = &aveOut;

Then defined the convection bc before iteration.

Code:

void prepareLattice(….){
bc.addConvectionBoundary(superGeometry, 4, omega, uAv);
sLattice.defineRhoU(superGeometry, 4,rhoF, uF); //rhoF=1, uF=(0,0,0)
}

Lastly calculated average velocity every time step and point it to the pointer
void getResults(){

Code:

IndicatorCircle3D<T> outflow( outCenter, outNormal, outRadius);
std::list<int> materials = { 1, 4};
SuperLatticePhysVelocityFlux3D<T,DESCRIPTOR>vFluxOutflow( sLattice,converter,superGeometry,outflow,materials );
int input[5] = {0};
T flux[5] = {0.};
vFluxOutflow( flux,input );

T meanSpeed= flux[0]/flux[1];
uAv=&meanSpeed;

}

I thought I did imposed the average velocity of the bc on *uAv.

I also tried to set a fix value to the *uAv. There was nothing different.

with best,
