hi, when i use "setParabolic
 
hi,
when i use "setParabolicInlet" application,it show:
setParabolicInlet /home/user/skolan/OpenFOAM/skolan-1.3/run/tutorials/sonicFoam backwardStep inlet 0.01 -z_noncenter -parallel -y_noncenter
-----------------------------------------------------------------------------

It seems that there is no lamd running on the host newton.

This indicates that the LAM/MPI runtime environment is not operating.
The LAM/MPI runtime environment is necessary for MPI programs to run
(the MPI program tired to invoke the "MPI_Init" function).

Please run the "lamboot" command the start the LAM/MPI runtime
environment. See the LAM/MPI documentation for how to invoke
"lamboot" across multiple machines.
-------------------------------------------------
how to fix it?thank you!
ps:I use OF1.4 IN SUSE10.2.

If you're using the setParabol
 
If you're using the setParabolicInlet that floats around here, be advised that it doesn't work correctly on parallel cases (at least the version I wrote). Therefore the -parallel option should not be used (and it only makes sense if you've got an mpirun, or similar, before the call to the solver.

hi. thank you for your answer
 
hi.
thank you for your answer.but now i do not know what can i do?

Try running it without -parall
 
Try running it without -parallel

hi, thank you!but it doesn't
 
hi,
thank you!but it doesn't work.it show
Usage:setParabolicInlet <root>.....-z_noncenter -parallel -y_noncenter,

Try setParabolicInlet . backw
 
Try
setParabolicInlet . backwardStep inlet 0.01 -z_noncenter
The dot is important. And the stuff iwht a - in front is optional
