Question regarding to viscoelasticFluidFoam on OpenFOAM-2.1.x
 
Dear all,
my name is Samir, it is my first time to use OpenFoam, I started reading and understanding the program structure, Kindly, I like to know, How I can embedd or install viscoelasticFluidFoam on OpenFOAM-2.1.x, shall I copy the files I download from http://sourceforge.net/projects/vffo...x.tgz/download to the OpenFoam directory, I am using ubuntu 12.04.
  • Please let me know the steps that I can follow in order to install or allow me to run any viscoelastic model without getting error in using the viscoelastic library.
  • One more question, is the provided code results validated and can be trusted.
thanks, and best regards.

Hi Samir,

Is it possible to install OpenFOAM-1.6-ext instead? That will come with viscoelasticFluidFoam and might make your a life a bit easier.

Dear Kyle,

Thanks for you replay, currently, I am working onOpenFOAM-2.1.x. Kindly, if you know, is it possible to write to me the steps of how to use viscoelasticFluidFoam on OpenFOAM-2.1.x

Thanks
Samir

Looks like you should decompress the tar ball in the ~/OpenFOAM/OpenFOAM-2.0.x/ directory. After that just run the install script:

Code:

./wmakeViscoelasticFluidFoam
It worked for me right out of the box.

Dear Kyle,
please, I like to ask one more question, I try to run one of the cases from the tutorial, viscoelasticFluidFoam, Oldroyd-B, it gave me the following error.

for running the tutorial case I first went to the Oldroyd-B tutorial test case directory, then I start with generating the mesh by using blockMesh, followed by writing viscoelasticFluidFoam for running the test case, so it gave me the following error, I do not know why it gave that error, could you please check it.
the tutorial like is http://dl.dropbox.com/u/80875880/Oldroyd-B.tar.gz

Thanks
Samir

BiCGStab (Stabilized BiCongugate Gradient) is a linear solver that is only implemented in the 1.6-ext version. Because you are using 2.x.x, Foam cannot find that solution method. There are a lot of hints in the error output that can help you understand the issue.

For Example:

These are the supported symmetric solvers that you might be able to use instead of BiCGStab:

Code:

Valid asymmetric matrix solvers are :

4
(
BICCG
GAMG
PBiCG
smoothSolver
)

Also, this is where Foam had encountered the problem:
Code:

Since this is a pretty entry level error you might want to spend a little more time running tutorials or doing the examples in the users guide. It might give you a better feel for troubleshooting.

Hi all
I want to compile viscoelastic solver but I faced this error:

Code:

  fatal error: viscoelasticModel.H: No such file or directory
Could you plz help me?
Thanks

> fatal error: viscoelasticModel.H: No such file or directory

Somewhere before this line you find which file is missing.
