Hi Experts
Can any one help to write a udf for convection difusion equation that contains a source term and a sink term. The project is to simulate the concentration of a radioactive gas in a model room. The wall and floor are the source of the gas (radon) d/dt(C) + div(uC) = div(D*gradC) +S- kC is the governing equation where D=diffusion coefficient of radon in air, K= decay constant ) |

Hi experts
Please suggest how do I approach this problem. Is the above mentioned governing equation built in its library? Where do I make changes using UDF? Thank You |
