Hi Mojtaba.
Thank you so much!!! It's really helpful. :) |
FSI-package with interFoam
Hello community,
i am starting my master thesis and try to run FSI simulations. I therefore downloaded the OpenFOAM extended 3.1 and the extend-bazaar FSI package, that is linked in this thread before. Now i am trying to add a solver based on interFoam for the fluid phase, by following the instructions in this report from chalmers university (chapter 4): http://www.tfd.chalmers.se/~hani/kur...FlowReport.pdf The solver is named interFlow, and i am failing at creating/preparing the InterFlow.C and interFlow.H files. I get massive problems when i try to compile it. Unfortunately my C++ skills are nearly not present, so i am asking if anybody already compiled such a solver, or can succeed creating one with the instructions in the given document, and can share these files. It would be a great help for me to go on inspecting the algorithms of a working FSI solver with gravitation, variable turbulence models and multiple phases included. Many thanks, Wowa |
New flow model
Hi Wowa,
Have you been successful in compiling the new flow model as mentioned in the report? Thanks, Arman |

Were you able to resolve the issue with parallelization of the fsi? I'm having the same problem. Please can you kindly share what you've learned so far. Thanks Samuel |
Dear Arman,
unfortunately i did not solve the issue to write an interfFoam solver for the FSI module, since single phase fluid flow was sufficient for my task. Dear Samuel, i managed to run parallel calculation on FSI problems with the foam-extend-4.0 extend bazaar fsiFoam solver. If you are interested in it, i can provide the solution with example files here this week. Kind regards, Wowa |
Dear Wowa,
Thanks men. Yes I'm very interested. My email is Anufagbemi24@gmail.com Thanks for your help Sam |
icoFsiElasticNonLinULSolidFoam runs parallel?
Hi guys,
It is crucial for a study that I'd like to do to know whether this capability has been added to icoFsiElasticNonLinULSolidFoam. It wasn't available in 2014. I am grateful in advance. Hossein |
fsiFoam parallel
Dear Samuel,
sorry for the delay. https://tubcloud.tu-berlin.de/s/rjXm8ncD8M9Sevm You can find attached a link to a simulation case based on foam-extend-4.0 next release solver fsifoam. It is a steel frame tower in water flow. The frame is modeled with the GMSH software. I changed several files from the beamInCrossFlow tutorial to create this simulation. Hopefully this method works for you. Don't hesitate to ask any questions. __________________________________________________ ________ To run the simulation just run the AllrunPar script following the number of processors, for example: ./AllrunPar 4 (Caution: if you do not submit a number of processors, the mesh will be decomposed infinitely. You then have to paste a number of processors in the decomposeParDict manually) __________________________________________________ ________ Also before running an fsiSimulation you have to go to the file: FluidSolidInteraction->src->fluidSolidInteraction->solidSolvers->unsTotalLagrangianSolid->unsTotalLagrangianSolid.C and change the two lines: 1596 //Switch moveMesh(solidProperties().lookup("moveMesh")); 1597 Switch moveMesh(false); into 1596 Switch moveMesh(solidProperties().lookup("moveMesh")); 1597 //Switch moveMesh(false); otherwise the solid mesh movement will not be saved and cannot be visualized. __________________________________________________ ________ Sincerely, Wowa |
