I have a problem when im running chtMultRegionSimpleFoam, my objective is to simulate a heat exchanger and everything works fine. My problem is that i want to determine the mean velocity in different sections were my waterflow is split. Therefore i need internal face in my fluid mesh but i havent figure out how to solve this? I do my mesh in ANSA so i need to set a specific face type there. I will use the bc at the face
".*" { type calculated; } Anyone have any idea? I dont want to spilit my fluid to more than 1 region. |

Dear Erik,
You should set the property type to Internal in ANSA and then output the OpenFOAM mesh. ANSA will put these faces into a faceZones file inside polyMesh Hope this helps Vangelis |

Thank you for the reply, i implemented the boundary condition and it works fine except i have some new phenonemas close to the internal boundary condition as you can see in the picture. So my question now for this boundary is ".*" { type calculated; } the right approach for this BC? Thanks Erik |

Hi Erik,
What do we see at the image? Velocity probably, zero at the wall? I assume what you see here is a matter of visualization and not a real result. Could you display the variables in Element and not Nodal position? Vangelis |
