Hello,

I am using the transport of diluted species module to simulate drug diffusion through the eye.

I need to give the concentration of the drug in the eye ball in terms of mg/cm3 but comsol is accepting values only in Moles/cm3

How do I get the software to accept values in mg/cm3?

C[mol/cm3] = C[mg/cm3]/(M[g/mol]*1000[mg/g])

Of course you need to know the molecular mass M of that drug.
