Dears,
I am going to simulate 3D rarefied gas flow through a micro-porous medium. The geometry
of a porous medium is given by boolean mask (0-gas nodes, 2-solid nodes, 1-intermediate nodes).
Now I need to implement the slip BC on the intermediate nodes.
I have tried to do it using
boundaryCondition->addVelocityBoundary1P( bb, lattice, boundary::freeslip );
were bb is:
DotList3D bb;
for (plint iX=0; iX<nx; ++iX) {
for (plint iY=0; iY<ny; ++iY) {
for (plint iZ=0; iZ<nz; ++iZ) {
if ( geometry(iX,iY,iZ) == 1 ) {
bb.addDot(Dot3D(iX,iY,iZ));
}
}
}
}
but I have failed.
Any help is highly appreciated.
best regards
