[petsc-users] Parallel FEM code using PETSc

[Farshid Mossaiby]

Thanks for your reply.
Indeed I want to expand the code to non-linear cases and use it as a study tool for some other researches. This requires plain C++ code to be available so that I can change different parts of it easily. Using a complex library unfortunately does not fit my needs for this research.

Hello,I’m not convinced the following will be find simple enough but Feel++ match the other expectations.In the example on the main page of the web site, you only have to change the line    a+=on(_range=boundaryfaces(mesh), _rhs=l, _element=u, _expr=cst(0.) );
to     a+=on(_range=boundaryfaces(mesh), _rhs=l, _element=u, _expr=expr(soption("functions.g")) );
and run the code withmpirun -np xxx ./feelpp_theApp --functions.g="2*x*y=x=y"
To change the bc you want to impose.I (highly) recommend Ubuntu 14.04 to test the library.
The documentation is hereYou may also have a look to FreeFem++All the best,VH​

Hi all,
Can somebody point me to a simple, linear, parallel FEM code based on PETSc, implementing efficient application of non-homogeneous Dirichlet BC? Domain decomposition code will is also welcome.
TIA
