[Nek5000-users] postx black window

Sun Oct 20 06:10:20 CDT 2013

Have you tried VisIt ?

There is much more support for VisIt than for postx.

Let me think about your postx problem --- it has something to
do with the X11 drivers and font sets, but I can't recall how
I've remedied this in the past.

Sorry to bother people in the list for this kind of naive question. 

I tried postx on two computers, one my laptop, one cluster in my laboratory. 

I got the same screen. It seems to be some graphics issue with the system. 

You can find the screenshot attached here. 

So what should I do? Thank you very much!

Hi Paul, 

Thank you for your response. 

I already put PATH = ~/bin:$PATH in ~/.bashrc 
running nekb is not a problem, the logfile gives the right results by using nekb or nekbmpi 
so the computation is ok. 

The question lies on postx 

I typed postx on the command line, then a black window appears, on the top of which there is "Nekton". 

but I do not see any sidebar 

And on the terminal, it asks "Enter Session Name" 

I left click the window with the cursor , and then "return" on the keyboard 

it returns on the terminal 

Enter Session Name 
Beginning Session 
renaming SESSION.NAME SESSION.NAME ~ 
Session name: 
** ERROR ** Can't open file .rea 
Enter Session Name 

XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0" 
after 235 requests (235 known processed) with 0 events remaining. 

What is wrong here? 

Thank you very much !

The easiest thing is to copy the nekb script to your working directory. 

There should also be a .soft file or something where you can add 

PATH = ~/bin:$PATH 

to get your bin directory into your path. 

hth, Paul

Hello, 

I am totally new to nek5000. I started with the pdf online to the case eddy_uv 

The computation seems ok, when I check the tail, I got the same results as in the pdf online. 

However, when I type postx 

I just got a black window, without any sidebar menu. 

In fact, when I compiled the tools in /nek5000_svn/trunck/tools/. 

I typed ./maketools all 

I got a lot of warnings, like 

CALL ZWGJD (ZD,WD,NP,ALPHAD,BETAD) 
1 
Warning: Type mismatch in argument 'alpha' at (1); passed REAL(4) to REAL(8) 
gfortran -mcmodel=medium -c mxm44f2.f 
gcc -mcmodel=medium -c -DUNDERSCORE byte.c 
gfortran -mcmodel=medium -c int_tp_gbox.f 
int_tp_gbox.f:574.28: 

But at the end, the compilation seems accomplished. 

So what is wrong with my installation? Thank you very much!
