Hi all

I wonder if there is a compressible nonNewtonian solver available for OpenFOAM..?

If not: would it be possible to alter the current compressible solver to handle nonNewtonian fluids?

And finally: I added a new viscosity model by copying and then changing the BirdCarreau model, but after compiling it's not working, since it is unknown to the solver:

-------
Unknown viscosityModel type vModel

Valid viscosityModels are :
<list>
-------

How can I let the nonNewtonianIcoFoam solver 'know' I added a new model?

I hope you can help me with this.

Kind regards,
Berry

In order to add a new viscosity model you have to recompile the transport library

- copy the new viscosityModels folder in
OpenFOAM-1.5\src\transportModels\incompressible\viscosityMo dels

- add a new line in the file "files" in order to add your new model during compilation

OpenFOAM-1.5\src\transportModels\incompressible\Make\files

- compile everything

Cd ~/OpenFOAM/OpenFOAM-1.5/src/transportModels
wmake libso incompressible

a new libincompressibleTransportModels.so will be created

now you can recompile nonNewtonianIcoFoam and the new model will be added

I don't know if you can creat a compressible model in the folder incompressible

Any answer to this? Anyone tried this?
