[Nek5000-users] Segmentation fault occuerd

Hi Fred,

You have an old SIZEu file -- the common block /DIMN/ should have the following structure:

      COMMON/DIMN/NELV,NELT,NX1,NY1,NZ1,NX2,NY2,NZ2
     $,NX3,NY3,NZ3,NDIM,NFIELD,NPERT,NID
     $,NXD,NYD,NZD

Recompile it clean.

Aleks

Hello,

I have some trouble to run my simulation... When I start running my 
simulation, I receive the following error-message (I compiled the run 
in debugging mode -g and with traceback):

forrtl: severe (174): SIGSEGV, segmentation fault occurred

--------------------------------------------------------------------------
mpirun has exited due to process rank 0 with PID 10816 on
node ifh-taifun exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).
--------------------------------------------------------------------------


By debbuging I've seen, that follwoing values in the subroutine 
set_conv_char (in convect.f) seem to be a little strange:
nxd=           0
nyd=     7457184
nzd=           0

In my DEALIAS-file the follwing line is commented out:
C      common /dedim/ nxd,nyd,nzd


I tried to run the simulation with the declaration in the DEALIAS-file 
and a      include 'DEALIAS'
in the subroutine set_conv_char (in convect.f) but the the run also is dying:

   ZWGJD: Minimum number of Gauss points is 1 -1633391248
  call exitt: dying ...


Do you maybe know where there might be my buck??


Thx a lot.

Fred
