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

Hi every body,

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 sebastian,

you have to change the patch type of your wall from patch to mappedWall in your boundary file.

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.
