[Nek5000-users] Three questions

[wangzhicheng]

 Hi,developers



Thank you for your Code. I'm really impressed with nek5000, although I have only known limited information as yet



1 The first question is about an error:

I run the turbJet case and get this errors

..........................................................................................................................................

 Number of processors:           1

 REAL    wdsize      :           8

 INTEGER wdsize      :           4





  Beginning session:

  /home/wzc/Code/nek5_svn/examples/turbJet/jet.rea                              



 

 timer accuracy:   1.1205673E-06 sec

 help:         600         600 -1700420800

2 What I intend   to do is  an accurate simulation of incompressible 
turbulent flow  (with heat  transfer)  around cylinders, my question is
:is nek5000 suitable for this simulation?

If it is YES, can I use the mesh generate tools included in nek5000 to create mesh for this case? 

I know you are working with Cubit, but I think it is not a free mesh generator.



3 the last: Is there any theoretical manual for me to understand the code ?  

I have some back ground on FVM, FEM , right now I study  the book "High-order method for incompressible fluid flow"







Many thanks
