Thanks for your answer, and sorry for my carelessness! The figure shown in the topic comes from my previous posts describing a different problem. In the current post, there are 3 phases- Phase A (primary phase), Phase B (secondary phase), Phase C (secondary phase). The phase condition in the inlet boundary is a combination of Phase A and Phase C (not present in the domain initially). I think that my trouble results from the domain I selected to patch covering the inlet boundary. Then when I specified the volume fraction of Phase C as 0.5, and patch the domain with volume fraction of Phase B being 0.59,the sum of the volume fractions of the two secondary phase at inlet boundary exceeds 1. I am wondering if there is an approach that can distinguish the inlet boundary and the patched region during initiallization. My goal for initialization is:the volume fractions of Phase A and Phase C are both 0.5 in the inlet boundary, while the volume fraction of Phase B in the blue region in figure equals 0.59.Â
