We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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
