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

[Walker, Ryan T. (GSFC-615.0)[UNIV OF MARYLAND]]

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
