Problem with SteamLine
Hi Foamers,
I'm Vincenzo and I have some problems with steamline in my solution. When I generate a map in Paraview I get image like these http://vici.oceanprosystem.com/U_steamlines.png http://vici.oceanprosystem.com/U_steamlines_section.png Instead, the result must be similar following http://vici.oceanprosystem.com/clip_image002.jpg Why the results obtained are difI would ask What's happen? |
Greetings Vincenzo and welcome to the forum!
Quick questions:
Best regards, Bruno |
Hi Bruno,
I'm sending the properties about steamline, where I use point source to generate steamline. http://vici.oceanprosystem.com/brunoproperties.jpg I don't understand when you say: single or several steamline filter? Vincenzo |

Hi Bruno,
I tried to follow your advice but however it doesn't work. I suspect in my simulation there is something wrong. For example, when I run my solver (simpleFoam), after about 600 iterations, the scalar p is stopped, but simulation go on for 2700 iterations. Infact I see the message: no iteration 1000. Why happen? What's mean? :confused: I send you the main folders of my case http://vici.oceanprosystem.com/0.zip http://vici.oceanprosystem.com/constant.zip http://vici.oceanprosystem.com/system.zip Regards, Vincenzo |
Hi Vincenzo,
Unfortunately I don't have enough experience to help you on this. Perhaps it's best that you ask this last question on the other dedicated sub-forum: http://www.cfd-online.com/Forums/openfoam-solving/ Best regards, Bruno |
Hi Vincenzo,
The "no iteration 1000" means: "number of iterations for pressure solver = 1000 iterations". The solution of the pressure equation system can't be improved any more. Your simulations convergence is fine and your initial residual for the pressure is already really low (for your mesh) after 700 iterations. You can add this line to the p solver settings in fvSolution: Code:
maxIter 50; // Default value is 1000; Martin |
Thanks so much Martin, now i'm spending my time in better way, fortunately. thanks Bruno, you are the light in the darkness XD
