Greeting all,
I want to implement follwing thermoPhysicalProperties in chtMultiregionSimpleFoam...
for rho -- incompressible & ideal gas
Cp -- piecewise polynomial
k, mu -- piecewise linear
According to this I have made the following changes...in thermoPhysicalProperties file...But after that is is showing following error...

[0] 
[0] 
[0] --> FOAM FATAL ERROR: 
[0] Unknown basicRhoThermo type heRhoThermo<pureMixture<polynomialTransport<specieThermo<hPolynomialThermo<incompressiblePerfectGas>>>>>

Valid basicRhoThermo types are:

)

What changes should I do to run it properly with the above condition....?
Kindly give some suggestion ......Thanx in advance !!!

Greetings Baran,

I received the PM you sent me. I'm in a bit of a hurry, somewhat just passing by here on the forum .
From what I can see, you didn't provide enough details to give you the solution you're looking for.

The best I can do is point out that there are only 2 major models available to that solver, according to the output you're giving, namely:

• hRhoThermo
• hsRhoThermo

But the one you have is "heRhoThermo".
Therefore, without more information, what I can also say is that you must - at all times - be very careful with every single detail, when dealing with OpenFOAM.

Good luck! Best regards,
Bruno

Greeting all,
I want to implement thermophysicalProperties for chtMultiRegionSimpleFoam in openFOAM 2.1....for this kind of properties... for fluid region...
rho-- incompressible and ideal gas
Cp-- piecewise polynomial
K---piecewise linear (value for some specific temperatures)
mu-- piecewise linear (value for some specific temperatures)

I go through the hRhoThermo & hsRhoThermo...not understand exactly...
I tried to set but unable to do it properly......Can anyone kindly suggest how to set this in OpenFOAM 2.1...??

Greetings Baran,

Sorry for the late reply, but only today did I finally manage to come back to your question.

From what I could figure out, you're trying to use a feature that was only made available in OpenFOAM 2.2.0. Because as the list you've gotten in the first post indicates, those options are not available in OpenFOAM 2.1.

Either you upgrade to OpenFOAM 2.2 (or 2.3), or you will have to back port the source code you need from OpenFOAM 2.2 to 2.1.

If you're curious where you could start, the source code files you need to look into are these two:

• From OpenFOAM 2.1.x: https://github.com/OpenFOAM/OpenFOAM.../hRhoThermos.C
• From OpenFOAM 2.2.x: https://github.com/OpenFOAM/OpenFOAM...o/rhoThermos.C

Best regards,
Bruno
