Hi all

Hi all,

In the openLB, is there a RotatingLinear2D functor? If not, how can I add this to the OpenLB?

Hi lbmcoding,

you can extend the source code by your functor. I recomment to copy an existing similar one. You are also welcome to email as the code to include in the next version of OpenLB.

Dear mathias,
Thanks for your reply. I have another question. When I handle a pipe flow simulation referring to the aorta3d examples, I found
that in my simulation, “regionName=inflow; regionSize[m^2]=0”, “regionName=outflow; regionSize[m^2]=0” why does this happen? Are the coordinates of inflow and outflow circle incorrect? Thanks very much!

[mathias]

It looks like they are incorrect!

Dear mathias,
Should I get their coordinates in the modeling software? As a general rule, how do we get this two coordinates?
And the normal vector should orientate the external geometry?Thanks!!

[mathias]

These parameteres depend on your actual geometry, so they come from outside!
