Re: [Getfem-users] Generic assembly brick crashes Matlab

[Yves Renard]

Dear Ryan, 

There was indeed a bug but not in the generic assembly. It was in the interface 
in the function
mfu=gfMeshFem(m);
which was not initialisating correctly the mesh_fem object. Instead, if you 
test with
mfu=gfMeshFem(m,1);
it should work. I committed a fix.

Thank you for the bug report.

Best regards,

Yves.

Unfortunately, I still get the crash with the latest development version, using 
the same example I gave in my last message to Yves (that is, using 
‘Grad_u.Grad_Test_u’ in demo_bilaplacian.m). 

I’m on Mac OSX 10.9.5, if that helps. 

Best regards, 
Ryan

Dear Ryan, 

would it be possible to fetch the latest development version of GetFEM++ from 
the svn repo, as described in 

http://download.gna.org/getfem/html/homepage/python/install.html 

and tell us if you can still reproduce the crash?

I’m trying to get generic assembly bricks working with the Matlab interface. 

The code "gf_model_set(md,'add linear generic assembly brick', mim, 
'u*Test_u’);” works fine. 

However, if I change the expression to something involving derivatives, like 
‘Grad_u.Grad_Test_u’ or ‘Hess_u:Hess_Test_u’, 
Matlab has an internal error (no specific error message) and shuts down. 

Based on the main C++ documentation, the expressions that cause Matlab to crash 
look legal. What’s going wrong here? 

I’m using version 4.3.2 with Matlab 2014a. 

Thanks, 
Ryan
