Hi Nakor,
this topic is interesting for me as well. I have only made first steps in source code modifications, but if you need support I will take a look at it. Maybe we can get it to work together. Regards, Michael |

after searching and deep looking in openFoam files i think that Ypmma and Ychar represent two components of solid material with properties for every material and concentration so by using solid mixture models the properties of calculated on basis of these components. please if any one has any idea about Ypmma, Ychar advice if this explanation is true or false. thanks in advance, |

Hi,
first of all i want to thank everybody who keeps running this platform. The user cremona described a problem in #14 and i have the same problem. Openfoam displays me the mistake:" patch type 'patch' not type 'directMappedPatchBase' .Can anybody explain what it is about and how to correct it? In my work i want to simulate the thermal diffusion between two solids, like the user cremona did. Thanks |

Hi Tobias,
i am happy for your quick response My wall Patch is of type mappedWall. I was inspired by your work done for the user cremona; dont know where the mistake is |

Well okay.
There are some changes between 2.1. and 2.0. I am using 2.1. and now 2.2. The case I added in this thread is for 2.1.x For y our problem have a look at the chtMulti tutorial and the patch types there. Use that one and everything should work. |

I am wondering have you solved thermal contact resistance between two solid domain? I am looking for something similar as thermal contact in COMSOL. https://www.comsol.com/blogs/thermal...ce-simulation/ Can you provide me some hints? Thank you. Liang |

i have the same problem. i'm solving electric potential on fluid and solid domains and i have different electric permitivity so i had to use chtmultiregion to implement it and successfully did it , but the problem is when i tried to differentiate the electric potential field on solid and fluid to get electric field , i couldn't get a continous electric field across interface like electric potentail , so do you any idea how to solve it ?

does someone could give me the answere if it is now possible in openfoam to account for contact resistance between two solids or not?
using esi v2112 |

actually i solved my issue
