HE ALL ;
I want to set Boundary condition for pollutant ( CO) as aditional variable my line source is in the ground a street at level z=0 . my Boundary parts are INLET, OUTLET, symetry ( SIDES 1 et 2) , GROUND , TOP , SOURCE the emission rate from the source is 0.0001 Kg/s. If any one experienced can help |

Sounds straight forward. Have you done the tutorials? That will give you some tips on how to get started.
Or what specific problem do you have in setting it up? |

thanks ;
firstly, I took a look in tutorial , there is an exemple wich treate smoke dispersion. My case deel with a tracer gaz (SF6) realised from a line source within a street. the emission rate is 0.0001 kg/m^3. To simulate the concentration of SF6 I used an additional varaiable CSF6 with a transport equation . I choose for CSF6 BC : INLET Value CSF6 =0 OUTLET ZERO FLUX SYMETRY ( SIDES) ZERO FLUX TOP ZERO FLUX GROUND AND LINE SOURCE CSF6 = 0 the simulate concentration CSF6 = f(Z) seems wrong because the minimum conentration value was located at level z=0 wich is not correct. |
