Hi T.D.
I'm fine. How are you? hope you are doing very well.
For your first question define nu_new in the create field as a volscalerfield and calcaulate it before using it in the code.
For your...

Hi T.D. If you did not get error it is true....

Hi T.D.
If you did not get error it is true. Use it.
For your second question. Beside any solver source code (i.e. icoFoam) there is a file createFields. In it pressure. velocity and other things...

Hi T.D.
How are you? I hope you are doing very well.
You are true. Examine:
volTensorField Gr=fvc::grad(U);
volSymmTensorField E = symm(Gr);
volTensorField GrTr=Gr.T();
volSymmTensorField Tr =...

Hi T.D.
How are you?
I hope you are doing very well.
As I know you can solve your problem in Cartesian coordinate with rotating BC on walls. If you want an analytical solution then cylindrical...

Cylindrical coordinates?

Hi T.D.
I hope you are doing very well.
As I know in OF equations are discretised in Cartesian coordinate. Would you please tell me why you are so interested in cylindrical coordinate? May be you...
