<DIV><FONT color=#000080 size=2 face=Verdana>Hi <FONT
color=#000000>Stefan</FONT></FONT></DIV>
<DIV> </DIV>
<DIV>Thank you for your reply!</DIV>
<DIV> </DIV>
<DIV>There are two other issue in the previous email which I hope you
can give me any adivice:</DIV>
<DIV> </DIV>
<DIV>1 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?<BR>If
it is YES, can I use the mesh generate tools included in nek5000 to create mesh
for this case? <BR>I know you are working with Cubit, but I think it is not a
free mesh generator.</DIV>
<DIV><BR>2 Is there any theoretical manual for me to understand the code
? It seems very difficult for me to understand what exactly the program is
doing without a guide.</DIV>
<DIV><BR>I have some back ground on FVM, FEM , right now I study the book
"High-order method for incompressible fluid flow" and "Spectral/hp element
methods for CFD"<BR><BR><BR><BR>Regards<BR><BR>Zhicheng</DIV>

<DIV>Hi,</DIV>
<DIV></DIV>
<DIV>nek tries to tell you, that the local size lelt is too small for the given number of elements and processors. If you have 9375 elements in total you probably need to run it in parallel. Your local size seems to be 600 elements so you need 16 proc to run the solver or you need to increase the local size lelt in the SIZEu file and recompile.</DIV>
<DIV></DIV>
<DIV>Hth,</DIV>
