Dear All,

maybe you can help.

i started to work with caelinux 2009.
after same trouble to have it working, i did resolv same FE probs.

but since PCLinuxOS was so complicated to wireless connect to 3 diferent place i have to be dayly. i decided to move to ubuntu.
now i do have wireless and every thing, but...
my salomemeca doesnt work. :(

i'll try to explain
download and tar zxf went ok.
python postintall, also went ok.
but as soon as i run comand "runSalomeMeca", it complains "command not found".
then i tried "./runSa...", i get

"rsimoes@rsimoes-laptop:~/Downloads/SALOME-MECA-2009.1-GPL$ ./runSalomeMeca
rm: remove write-protected regular file `/home/rsimoes/.pal_salome2/AsterConfig2009.1'? "

is this normal????

so i tried with sudo, still complains "command not found".

then i did
"sudo shh"
"# runSalomeMeca"
"sh: runSalomeMeca: not found"
folloew by:
"# ./runSalomeMeca"
finnaly its starts. :)

i can activate the aster module.
but when i run the solver i get:
"error while writing astk report file"
then i've recompute the mesh and export,
and now when i solve with aster, it opens a window, as if to start solving, and imidiately closes this same window. and reports "<F> System".

and i can see this error in cas file:
"WARNING : ASTK Server version 1.7.1 differs from
ASTK Client version 1.6.2.
An update from Server or Client is necessary.
This execution may fail ! "

is this the reason?
can i update the cliente?

greetings

You always need to add./ to runSalomeMeca when launching it from its folder - otherwise it will look for the executables in /usr/bin etc etc.

You wont need to use 'sudo' for salome-meca unless you need superuser privileges - which you shouldn't.

It sounds like the configuration of salomé is broken somehow; try deleting ~/.astk* (everything called something with .astk), delete salome-meca and extract it again and run 'python postinstall.py' again.

Give it a try and come back if it's still broken :)


edit: also remove everything named *salome* in the home folder - like the .pal_salome file.<br /><br />Post edited by: Claus, at: 2010/05/20 01:39

Yes,
in fact, most of the problems when running an Aster job from Salome Meca or ASTK are because of &quot;interactive&quot; mode.
Disabling it will most probably solve 90% of the issues.

To have interactive mode working, you need to make sure that:

1) you can open a X terminal from &quot;localhost&quot; so check if you can run :
[code:1]xterm -display localhost:0[/code:1]
if not, you need
a) to enable remote X windows TCP connexions, Usually it is done by changing the gdm or kdm configuration files. On recent Ubuntu (9.10, 10.04), you need to edit /etc/gdm/gdm.schemas to change DisallowTCP to false
b) then modify your .bashrc to add one line at the end:
[code:1]xhost +localhost +$HOSTNAME[/code:1]
this will allow all X window connexions from local machine
c) check again if Salome-Meca / ASTK can run the job in interactive mode
2) If this is not sufficient, this probably means that ASTK considers your machine as a &quot;remote server&quot; (this can be due to some misconfiguration of DNS / hostname or because of DHCP...); in this case, you need to install OpenSSH and configure it to have &quot;password less&quot; connexions (see www.csua.berkeley.edu/~ranga/notes/ssh_nopass.html for example). In ASTK then, choose the remote protocols = SSH and SCP.
Now the last check:
[code:1]ssh localhost xterm -display localhost:0[/code:1]
This should normally work now... and the &quot;interactive&quot; execution of Aster should work too.

Hi Administrator,

did what you said, and i can now run the

&quot; xterm -display localhost:0&quot;
and
&quot;ssh localhost xterm -display localhost:0&quot;

both work great.

still i cant run the aster case in interactive mode.

thats not a big deal, since i can solve.

there is still one prob i cant solve, but i'll post it in the right place.

thanks lads,
rui
