Hello,

I am working with big finite element matrices (64000 x 64000) using sparse function with Matlab.

However, in order to inverse one of these matrices, Matlab and sparse are not efficient anymore.

I heard that Nastran can be used to do it ...

Would anyone know something about it ?

Thanks a lot.

Alain
