Hey Foamers,
I am simulating ice formation on wind turbine airfoils so I am injecting water droplets at temperatures < 273.16 deg K in reactingParcelFoam (OF6). When I do that....I received the following error: Code:
#0 Foam::error::printStack(Foam::Ostream&) at ??:? #1 Foam::sigFpe::sigHandler(int) at ??:? #2 ? in "/lib/x86_64-linux-gnu/libc.so.6" #3 ? in "/lib/x86_64-linux-gnu/libm.so.6" #4 pow in "/lib/x86_64-linux-gnu/libm.so.6" #5 Foam::H2O::rho(double, double) const at ??:? #6 Foam::regionModels::surfaceFilmModels::liquidFilmThermo::rho() const at ??:? #7 Foam::regionModels::surfaceFilmModels::thermoSingleLayer::correctThermoFields() at ??:? #8 Foam::regionModels::surfaceFilmModels::kinematicSingleLayer::preEvolveRegion() at ??:? #9 Foam::regionModels::surfaceFilmModels::thermoSingleLayer::preEvolveRegion() at ??:? #10 Foam::regionModels::regionModel::evolve() at ??:? #11 ? at ??:? #12 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #13 ? at ??:? Floating point exception (core dumped) Thank you in advance. Regards, Khaled |

Hi all,
I have found a work-around that can temporarily solve the problem but not completely. In surfaceFilmProperties, I put filmThermomodel = constant and I put constantCoeffs with the following values (values correspond to water at T = 273.16 deg K): Code:
constantCoeffs { specie H2O;//all properties at 273.16 deg K rho0 999.8; mu0 1.792e-3; Cp0 4217; sigma0 0.07; kappa0 0.561; W0 18.0153; Tb0 100; pv0 611.3; hl0 2501e3; D0 2.09e-5; } if somebody has a better idea, please share it.
