Hi all!

Is it possible to output the global stiffness matrix of a model at a certain time-step?!

Thanks!!!

not at the moment .. you could always
go into one of the system of equation objects and make the change yourself in the source code.

Thanks for your kind answer!

Unfortunately I really don't know how to manage the source code. Can you give me any reference about this subject?!

Thanks!!!

why don't you have a look at the source code for one of the solvers .. BandSPD is pretty simple .. you basically at a solve want to print out the contents of the matrix.

if it looks way too complicated you need to learn some basic C and C++ programming!
