Dear Gianmarco,

I have tried to copy the filename_eig_0 to filename_eig_0.fld and processed this field with FieldConvert. A file named filename.vtu is created and then visualized with paraview. But, nothing was shown in paraview. I then looked into the filename.vtu and found that all variables such as u ,v w, p existed, but the cell number is zero. I am sure the solution was converged, and I have tried many times, but all failed (I have tried version 4.01 and 4.10 ).

Then, I am going to try to use the branch fix/INSCoupledStabilitySolver. I don't know if it is a right operation:

step 1, I downloaded the last code with Git (git clone http://gitlab.nektar.info/clone/nektar/nektar.git nektar++) and compile it in order to use the branch fix/INSCoupledStabilitySolver.

step 2, I have used the BiGlobal Floquet analysis to acquire filename_eig_0 file and used FieldConvert to create .vtu file.

But it doesn't works ( same problems as above)
So I am confused. Please help me. Thanks very much for your help!

Best Regards!

Dear Hongfu,

you can just try to use the following command:

FieldConvert filename.xml filename_eig_0.fld filename_eig_0.vtu

in order to get a vtu file which can be then loaded into Paraview.

Please, note that I have explicitly added the extension .fld to your original filename_eig_0 - this is to allow the postprocessing routine to avoid the error you may have encountered trying to convert it.

Let me know if this works.

Best regards,

Gianmarco

Hi All,
I want to computethe eigenmode of a period field using BiGlobal Floquet analysis. I have gotten the "filename_eig_0" like file, how to do post-processing with this kind of file?

Thanks very much for any help!

Best Regards!

Hongfu
