[Nek5000-users] How to add Coriolis force

[nek5000-users at lists.mcs.anl.gov]

Hi,Mike
   Thank you very much for you help. Now I have a question about the built-in variables. As the help document is not so sufficient, there are so many variables not introduced, so how can I find what's the meaning of the variables? I'm sorry to trouble you for this simple question, but it's really important to me.


Thank you
Xianbei
