Hi all,
I'm using fsiFoam and I want to specify multiple patches as Solid and Fluid Interfaces. How can I write this list? Here is an example of the dictionary: Code:
/*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | foam-extend: Open Source CFD | | \\ / O peration | Version: 3.0 | | \\ / A nd | Web: http://www.extend-project.de | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; object fsiProperties; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // solidPatch coda_top coda_bottom coda_end; solidZone coda_top-zone coda_bottom-zone coda_end-zone; fluidPatch coda_top coda_bottom coda_end; fluidZone coda_topzone coda_bottomzone coda_endzone; relaxationFactor 0.1; interfaceDeformationLimit 0; outerCorrTolerance 1e-4; nOuterCorr 200; interpolatorUpdateFrequency 0; //couplingScheme FixedRelaxation; couplingScheme Aitken; // couplingScheme IQN-ILS; couplingReuse 0; coupled yes; // ************************************************************************* // Thanks. |

Hi,
By looking at the source code, it can be seen that the fsi toolkit only supports one coupled patch at the moment. Have you tried putting all of the patches in a single patch or you need different boundary conditions for each patch? |

Hi
I have 4 beams and combine all paths to one with createpatch and use the fsiFoam to simulate. the result has shown no motion of beams while this model simulated with Fluent and icoFsiElasticNonLinULSolidFoam solver and has motion. I also change solidSolver to IncrLagrange but deformation of beams was wrong. |

It might be something else that causing those 4 beams not to move. |

Dear Khazaei
Thanks for reply. Before I check the results with icoFsiElasticNonLinULSolidFoam solver. Now I check results with Fluent and it seen (after 0.2 s) has agreement with Fluent results. I think the fsiFoam solver has reliable results than icoFsiElasticNonLinULSolidFoam solver and the createPatch has work good. Thanks |
