When I open U for example, I find:

dimensions      [0 1 -1 0 0 0 0]

That means m/s

What are the other dimensions?

    $\begingroup$ This is a question specific to OpenFOAM -- which you should ask on the OpenFOAM-specific mailing lists and forums because that's where the people who know this software hang out. $\endgroup$ Aug 31, 2018 at 21:10
  • $\begingroup$ I know, but i was trying to use this stack to gather people that use openFoam here. Then we can create a CFD stack community and migrate those questions. I tried on arena51 to create CFD stack but it didnt have enough visibility. @WolfgangBangerth $\endgroup$ Aug 31, 2018 at 21:20
  • $\begingroup$ @WolfgangBangerth , to sum up, You are right. As you said people that know this software are not here. So i was thinking about to ask and answer myself many questions to bring them here. $\endgroup$ Aug 31, 2018 at 21:24

    $\begingroup$ I don't think posting fake questions and then answering yourself is an approved strategy. The thing really is that if you can't find a critical mass of people answering questions on the OpenFOAM specific forums, then you're not going to find that critical mass anywhere else either. $\endgroup$ Aug 31, 2018 at 22:09

    $\begingroup$ The question was already closed, so the point is moot. But what I'm saying is that you seem to want to create a forum where people can post their OpenFOAM-related questions. The thing is that that only makes sense if they can actually get answers there as well. But just because you have answered a few of your own questions doesn't mean that there is a critical mass of OpenFOAM-experienced people here who can do that for other questions. $\endgroup$ Sep 11, 2018 at 3:35

Units on the brackets follow the figure:

Accordingly, [0 1 -1 0 0 0 0] = m/s
