Hi there, I'm very new to FLow simulation and SW as a whole. I have designed a sprinkler head from a fire sprinkler system and am currently trying to run a simulation to analyse the flow of water through it. I have built the assembly, set up the parameters of the simulation but when I click run the dialogue box that opens sems to stop after 4 or 5 seconds with the indicator 'basic mesh generation' along the bottom. I am unsure if the program is perhaps generating a mesh and it's just taking a long time ( >30 minutes) or if I must do it myself, again I'm unsure how this is done. Any help would be massively appreciated as I'm on a tight schedule!!
