Blockmesh for swimming cylinder
1 Attachment(s)
Hallo,
I'm new here and i'm new with OpenFoam. So i work at simulation of swimming cylinder in waves. I've started to wright blockMeshDict file. As reference for mesh generation i have took an example from ProgrammersGuide.pdf (openFoam parent dir. -->) page 47 ff.. So i want to see what i' ve done in Paraview, but there is a problem with block mesh. After typing in Terminal "blockMesh" from my case dir. i've got error that looks like: --> FOAM FATAL IO ERROR: Failed wmake "dynamicCode/_d908cad1f0f5da63365b2a5dd0f6be17536ee27d/platforms/linux64GccDPOpt/lib/libcodeStream_d908cad1f0f5da63365b2a5dd0f6be17536e e27d.so" file: /home/v000v/OpenFOAM/v000v-2.0.1/run/tutorials/multiphase/interDyMFoam/ras/FLNG/constant/polyMesh/blockMeshDict from line 17 to line 17. From function functionEntries::codeStream::execute(..) in file db/dictionary/functionEntries/codeStream/codeStream.C at line 210. FOAM exiting Can anybody offer a solution for my problem? |

Hallo again,
I've got a couple of problems under control, so I've change a little bit my blockMeshDict. Now i've got another one. I think that the problem is in a mesh at the edge between cylindrical mesh and the rest. That the faces are not identical on the both sides of edge. How can I assemble my mesh so that there are same face number on the both sides of the edge? Should i calculate it by side and arrange my mesh there for, or is there some skripts or other tricks to get the mesh works? Thanks! |

Hallo again,
I've got my mesh to view. I have a problem with a boundary conditions in the mesh. "Down" should be my symmetry plane, so I have define all faces in this plane. Terminal massage says that a couple of them have no neighbor cell. If i write these faces as comment, then turns openFoam in Paraview these faces to default faces and this pretty ugly. So can anybody take a look at my Mesh and explain me what the case is? Thank you guys. |

Hi,
there were four minor problems, their correction marked with "// <---". Should work now. Martin |
Probably your facelist for some patches is not complete. Boundary faces that are not assigned to a patch form a seperate patch. This is probably what happened here.

P.S. too much points and blocks to hold overview. Thank you! |
