I have been facing problem in using ansys cfx for fracis runner simulation. The result was found to be undesirable. I am using turbo grid and turbo mode. I have attached all the pictures related to inlet, outlet, boundary,domain setting and result. The total mass flow rate is 2350 kg/s and m using 138.5 kg/s per passage. I dont know using /passage /component and /machine. I am carrying simulation for single blade. And i wanna know if the outlet domain works as draft tube?? Please go through all the pics and suggest me some solution. Your help will be appreciated. thank you. streamline is different. the velocity was found to increase at outlet. outlet velocity is larger than of inlet. but the outlet velocity is to be nearly 1-3 m/s as of draft tube.domain.jpg
