I am working on improving the thermal performance of microclimate by using heat mitigation measures i.e. water, vegetation, and materials ets, particularly the water impact on temperature reduction in the surrounding area of the microclimate. I am using Ansys Fluent with species transport model switched on. Since water and computational domain both are fluid zones; thus there exists an interior zone between the two fluid zones. When I run the simulation with water liquid material assigned to the water zone and mixture material to the computational domain, there exists an error species are not solved in the neighboring thread cells of the interior zone which disappeared with mixture material assigned to both water zone and fluid zones and by considering water zones sides as wall with water material properties since these are only two methods to solve species in the overlapping region of two fluid zones. I just wanted to confirm whether simulation results with mixture material assigned to both water zones and fluid zones produces accurate results or by considering water zones sides as walls with water material properties produces accurate results? Please guide me so that I can proceed accordinglyn

When I run the simulation with water liquid material assigned to the water zone and mixture material to the computational domain, there exists an error " species are not solved in the neighboring thread cells of the interior zone" which disappeared with mixture material assigned to both water zone and fluid zones and by considering water zones sides as wall with water material properties since these are only two methods to solve species in the overlapping region of two fluid zones. I just wanted to confirm whether simulation results with mixture material assigned to both water zones and fluid zones produces accurate results or by considering water zones sides as walls with water material properties produces accurate results?
