Hi all,
i try to simulate a flow in a pipe. in the middle of the pipe, i try to implement a valve which should open when the pressure difference is high enough otherwise it should be closed. so, are there any examples in the tutorials where valves are used? how can i implement a valve? thx for reading and i hope you make some suggestions. |

Hi thx for your answer.
i am new to OF so i donīt understand those scripts at all. my problem is quite simple, i think. must i really create those scripts or are there any easier ways? or what elements can be copied for this problem? thx for your patience |

If you want to simulate s.th. with a real physical meaning (and behavior of an valve) you should take a deeper look into this stuff. An alternative might be a Boundary Condition that behaves according to your valve but not much easier to implement in my opinion. Are you doing a real world engineering problem or is your stuff going more in the gaming direction? In case of gaming take a look at blender and its cfd capabilaties. Not bad at all! To read more the about the "advanced" stuff you want to do http://web.student.chalmers.se/group...ynamicMesh.pdf At the workshop in Gothenburg the "advanced users" gonna work on OF's dynamic mesh capabilaties that includes valves. Not easy for a beginner! elvis Last edited by elvis; June 19, 2010 at 07:29. |
