cyclicAMI issue for infinitely long circular cylinder
Hi,
I am trying to simulate flow around a circular cylinder. To mimic infinitely long span, I want to use periodic BC on the two sides spanwise (span length is 8 and origin is located in the center of the cylinder). mesh was made by cfMesh so cyclicAMI instead of cyclic type is used. boundary patches are as follows: inlet (in flow direction, -x) outlet (in flow direction, +x) top (in cross flow direction, +y) bottom (in cross flow direction, -y) side1 (in spanwise, -z) side2 (in spanwise, +z) so in polyMesh/boundary, I applied cyclicAMI as follows: side1 { type cyclicAMI; nFaces 28010; startFace 12947067; neighbourPatch side2; matchTolerance 0.0001; transform translational; separationVector (0 0 8); } side2 { type cyclicAMI; nFaces 28010; startFace 12975077; neighbourPatch side1; matchTolerance 0.0001; transform translational; separationVector (0 0 -8); } assuming laminar flow, I applied cyclicAMI to 0/U and 0/p as follows: "side1|side2" { type cyclicAMI; } Update: fixing typo and separationVector sign get to work. |
Hi
I have got the same problem, and I haven't solve it yet.So I reply your post, and wait for the result. |
