Hi,

I'm trying to make your code work on my PC, but i'm stuck on this error. Do you have any idea what can cause that ?

Thanks

I think there is a small issue with the initialization of the vector used in our implementation of lobpcg. Have you tried using the lobpcg/pinvit included in ngsolve? I think it is fixed there
