HI all,
I want to get the concentration values of particles in oil,and i am tyring to use the models of Transport of Dilutes Species（tds） and Turbulent Two-Phase Flow，Level Set(tpf) . The initial concentration is 10^(-12)mol/m^3, but there are negative values in the calculation results，and the negative values is about -10^(-12)mol/m^3.
when the initial concentration is 1mol/m^3, the negative value is about -0.01，which can be accepted.
I want to know whether the COMSOL software is suitable for the calculation of my case，in which the concentration values of particles are small.
Does anyone have a similar problem?
Thank's in advance,
Liangwang Wang
