Hi,
i have quite an issue with my matlab-comsol connection. I open the Comsol model, then I go file -> client/server/matlab -> Connect to matlab. Matlab starts ok. When I tell matlab to run the comsol script I have opened this way, it asks me about changing directory, I allow it to do so and then it simply disappears without saying anything. I cant even close the Comsol window that remains on afterwards, because it can not disconnect from the matlab which disappeared. I'm totally puzzled. Please help !

Hi,
I have searched the problem a little and it seems to bee an geometry issue. In script, which uses imported geometry, it falls on
fem.geom=geomcsg(fem);
in scritpt, that creates geometry itself, it falls on
g5=geomcomp({g3,g4},'ns',{'g3','g4'},'sf','g3+g4','edge','none');
(previous set of commands :
garr = geomimport('/home/hanz/Dokumenty/COMSOL/scripting_exp/brzda/brzda_geom.mphbin', ...
'repairtol','1.0E-5', ...
'sdim',3);
[g1,g2,g3,g4,g5]=deal(garr{:});
% Geometry objects
clear s
s.objs={g1,g2,g3,g4,g5};
s.name={'CO1','CO2','CO3','CO4','CO5'};
s.tags={'g1','g2','g3','g4','g5'};
fem.draw=struct('s',s);
)
where the g3 and g4 are :
g3=rect2('0.02','-0.0075+0.06','base','corner','pos',{'0.06','-0.06'},'rot','0');
g4=rect2('0.06','0.02','base','corner','pos',{'0.08','-0.06'},'rot','0');
simple rectangles.
Any thoughts ?
Please help x 1000
Thnx,
Hans

Sorted out by using older matlab. When tracking error, the thread goes somewhere outside the COMSOL m-files.
