Can you tell me how you solved the problem with the error: Unknown polyPatch type ? I tried to create my own boundary but blockMesh can't find the library i created with wmake libso. Thanks a lot

Hi Mike
I could run the code in parallel with 2 processors in the x direction, but when I tried reconstructPar I got Reconstructing FV fields Reconstructing volScalarFields EP > FOAM FATAL ERROR: request for polyMesh solid from objectRegistry liquidprocessor0 failed available objects of type polyMesh are 1 ( region0 ) From function objectRegistry::lookupObject<Type>(const word&) const in file /build/buildd/openfoam1.6ext1.6.0/OpenFOAM1.6ext/src/OpenFOAM/lnInclude/objectRegistryTemplates.C at line 140. FOAM aborting Aborted  I am really surprise that reconstrucPar looks for the directory liquidprocessor0 my main directory is liquid Any comments are welcome!

Hi Aram
Did you solve your problem? Could you please tell what did you do? Thanks Alberto Quote:

Hi!
I think this problem was solved with OF 1.6. Concerning your problem with reconstructPar, you can only reconstruct fields from specific regions, e.g. reconstructPar region <regionName>. Hope that helps! Cheers, Aram

Hello Foamers
I am trying to use decomposePar for the geometry sketched below, fluid domain with a solid domain which length is a third of the liquid length, until now I can only run conjugateHeatFoam solver using 2 processor for the liquid and 2 for the solid (xdirection), is there a way to use at least 6 processors for the liquid and 2 for the solid (or more), I have found the instruction globalFaceZones ( nameofzone1 nameofzone2 ); but I do not know how it works or if it is useful for my problem, Using more than 2 processors I have observed that theres is not regioncouple between processor L0 and S0, how can I solve this issue? Please let me know your opinion about this problem Any help is welcome. Thanks in advance. Alberto

Hi,
Has anyone succeded building conjugateHeatFoam solver in OpenFoam other than 1.6ext?

Hi Foamers,
How i can define temperature dependent diffusivity in fluid region in conjugateHeatFoam solver? for example DT=a+bT ???

Hi,
In conjugateHeatFoam solver that released in OpenFoam 3.1 ext in polyMesh section there are bridge over lap and master,anybody know what do they mean??? another question is that how can i define a constant temperature piece that cooling down with a fluid? in 1.6 ext version with internalField i can do this but in 3.1 ext i can't!!!

Dear Hrvoje Jasak,
It is a very good concept that I would like to use for multiphase flow. Thanks for the implementation. I tried to understand the boundary conditions chtTemperature and chtRcThermalDiffusivity in foam extended 4.1. The first boundary condition asks me diffusivity field other than remote field. The problem for multiphase flow is that conductivity of solid is diffusing which makes the diffused conductiivity in the liquidgas mixture since they are coupled. I could not find the exact piece of code that makes this diffused conductivity(because of harmonic mean you implemented or from thermodynamic libraries?). I would like to keep the solid conductivity uniform everywhere. However as the liquidgas interface moves, I would like to couple it with solid domain. Could you give me any idea? Thanks, Best Regards,
