Hi,
I use interFoam to simulate bubbles in glycerine, I obtained bad results, and I don't know what is the numerical problem. With water there aren't problems. I use this solvers { pcorr ICCG 1e-10 0; pd ICCG 1e-10 0; gamma BICCG 1e-12 0; U BICCG 1e-08 0; } PISO { momentumPredictor yes; nCorrectors 3; nNonOrthogonalCorrectors 0; nGammaCorr 1; nGammaSubCycles 4; cGamma 2; Image1 Image2 Image3 http://www.cfd-online.com/OpenFOAM_D...your_image.gif Regards |
Is it only the density and vis
Is it only the density and viscosity that differs between water and glycerine?
Did u try changing one thing at a time to find out what made the changes? Regards /Joakim |
only the viscosity is the impo
only the viscosity is the important change; for water is 0.001 and for glycerine is 1.045, (density: water 1000, glycerine 1257; and surface tension: water 0.07, glycerine 0.063)

OK, sorry I do not have any id
OK, sorry I do not have any idea for the moment.
I have a question though. Did you initialize with a spherical bubble. If so how did you accomplish the initialization? Regards /Joakim |
the initial condition is this
