| Summary | 0003467: Addition of viscoelasticFluidFoam solver | ||||
| Description | Hello everyone, For a project I needed viscoelasticFluidFoam to work so I patched it from ext4.1 to the current dev tree. All seems to be working fine so far and I can run solutions on it now. Corrected the solver, transportmodels and all tutorials (except 1 blockmesh that i still have to work on) to properly compile and run without errors in dev. Info can be found in my github with the development branch. https://github.com/tomracing79/OpenFOAM-dev/tree/viscoelasticFoam I would like to do a pull request in the end when I've updated master and finished a succesfull branch merge but would like feedback before I do so. Also a question about what to do with the headers in the files and how to attribute the work to the original authors? Regards, Tom | ||||

Viscoelasticity in OpenFOAM does not need a special solver, it is handled within the TurbulenceModels framework as a special laminar sub-set so that it can be used in any single-phase, multiphase, incompressible or compressible solver. Currently Maxwell, Giesekus and PTT models are supported in both single mode and multi-mode operation and other models can easily be added. See tutorials: incompressible/pimpleFoam/laminar/planarContraction multiphase/compressibleInterFoam/laminar/climbingRod |

Dear Henry, thank you for pointing this out. Sorry I hadn't noticed this improvement was there already. In any case it was an interesting exercise in C++ debugging. I will first compare the results to see if they are identical and then try implementing some other models. Would that be of interest to contribute in the end? |

Which other models are needed for which fluids? |

Viscoelasticity is already supported in a more general manner in OpenFOAM. |
