Hi Guys
Can fluent solve viscoelastic fluids, I have heard polyflow can do that, Many thanks |

Hi,
analyzing viscoelastic fluids is my M.S. thesis. FLUENT can't model that. you can use polyflow that is included in ansys 12.1 and later but it's not user friendly and has some restrictions. finally I prefer switch to OpenFOAM. |

Hi,
U mean polyflow is another commercial code which is provided together with ansys fluent 12.1? What are the restrictions for polyflow? Please also let me know if openfoam is user-friendly and if it is expensive to buy? Is it possible to imply viscoelasticity through UDF in fluent? thanks |

Hi hamid,
polyflow is a commercial software included in FLUENT 12.1 and 13. about restrictions, e.g. it can't involve dynamic mesh with viscoelastic solvers. but OpenFOAM is an open source code package and also free and open distributed. it's better to use OpenFOAM under LINUX OS. to use that you should dominate on CFD schemes. codes were developed in C++ language. for real viscoelastic flows which has elements for storing and damping energy you can't use FLUENT. |

Thanks for all the helps, then as I understand openfoam is not user friendly code, is it possible to use it with windows?
If I don’t have dynamic mesh can I use polyflow without problem? Comparing polyflow and openfoam which one is easier and more straightforward to use? |

I think OpenFOAM is not user familiar but it's user friendly if you like programming.
note that you can change specific parts of polyflow by predefined macros (something like UDFs) but in OpenFOAM you can generate your own solvers easily.(it may be necessary for various viscoelastic solvers). I prefer OpenFOAM because everything is under control unlike polyflow. OpenFOAM was also released under windows OS but some utilities were lost and I don't recommend you. about other restrictions of polyflow, I'm not sure, you can ask other guys about possibility of your case in polyflow. regards, Amir |
