Hi everyone,nI would like to know how can I set secondary phase as mixture in the VoF model.nMaterial in primary and secondary phase is air and TMAH solution separately.nI define TMAH as a new material in fluent.nI think that TMAH can dissolve in water and then TMAH solution should be set as one phase in the VoF model.nI try to use species model to set a mixture include TMAH and water.nProblem is that I can't edit mixture in material panel.nHow can I solve it?.Thanks,nLisa.n

If you're using a mixture of TMAH and water in the liquid phase you assign the materials (species mixture) to the phase. For a mixture you also need to switch on species. However, assuming the liquid phase is a solution with (more or less) constant composition I'd just alter the properties to suit. n

Enable Multiphase create your materials. Then enable Species for Phase-2. Select default mixture. Afterwards modify that mixture to contain what you want .n
