Is it possible to develop a UDF for the relaxation time (coeff) in Lee's Model in Volume of Fluid (vof)? The coefficient depends of density of liquid (rho_L) and vapor (rho_v) and other parameters. See the equation below the definition of the coeff in Lee's model below:October 29, 2020 at 12:20 amSurya DebAnsys EmployeeHello, nYou can use DEFINE_LINEARIZED_MASS_TRANSFER or DEFINE_MASS_TRANSFER UDF for this. Please check this link which shows an example to customize mass transfer in multiphase case using UDF. nI hope this helps.nRegards,nSuryanOctober 29, 2020 at 7:34 amDrAmineAnsys EmployeeBetter to write the UDF for mass transfer as Surya highlighted.nViewing 2 reply threads
