Good day, I am conducting an analysis with the intend of finding the velocity of flow over a diverter from a nozzle, but I could not seem to set the boundary conditions as intended.
I have attached a 3D file that I used.
I would appreciate any feedback and advice provided.
Thanks.October 12, 2020 at 9:21 amDrAmineAnsys EmployeeCan you highlight inflow and all other boundaries used? (PS: Ansys Stuff do not look into attachments)nOctober 14, 2020 at 12:28 amOctober 14, 2020 at 9:40 amRobAnsys EmployeeTry adding a velocity to the inlet: you set 0m/s?nOctober 16, 2020 at 1:45 amjjyy555SubscriberHey Rob, yes I have tried changing the inlet velocity as well but to no avail.nOctober 16, 2020 at 10:53 amRobAnsys EmployeeCan you check the inlet is actually attached to the domain. Carefully looking at your boundary conditions I can't see an inlet; I can see several mesh interfaces so I wonder if your inlet isn't actually doing anything. nOctober 17, 2020 at 8:33 amjjyy555SubscriberI assigned the wall at that location to be the inlet, don't suppose that interface is connected to the domain?nIf possible, can I trouble you with a ZOOM chat on Monday?nOctober 19, 2020 at 11:09 amRobAnsys EmployeeWe're only able to communicate via the Forum: this protects us from US Export Law. nIf you have an interface there I think you're adding material into a different part of the domain. Go back to the CAD and use Share Topology (SpaceClaim) or create a Multibody part (DesignModeler) and it may be easier to set up. nOctober 19, 2020 at 1:00 pmjjyy555SubscriberAlright, will try. Many thanks.nJust a note, I initially designed the components in Autodesk Inventor then exported the file as a .igs file.nOctober 19, 2020 at 3:49 pmRobAnsys EmployeeThat's fine, you can still do share topo and the like in the Ansys geometry tools. We often use CAD from third party software for projects. Try using Step format, IGES is notorious for being awful. nOctober 20, 2020 at 8:30 amjjyy555SubscriberOctober 20, 2020 at 10:58 amRobAnsys EmployeeIf you create a New pathline you can add it to the objects as normal. You can't make them transparent though. Skip is a goo option to give more clarity, along with colour by particle time. nThere isn't much you can do with pathlines as they just create the lines. Have a look at mass less particles and the Particle Track option Pulse. nOctober 21, 2020 at 6:19 amjjyy555SubscriberThanks Rob, I think I got most of what I need.nCheers.nViewing 12 reply threads
