Hello, I am a new FEniCS user. I have a problem with a 1D cantilever problem which would be very easy for you. My problem is as blow: u’’[x] == - M/EI BC: u[0] = 0 u’[0] = 0 And my code is as below: > from fenics import * > > E = 200e9 > I = 1/12*0.0001 > M = 500e3 > tol =…

You cannot prescribe both a Neuman and Dirichlet condition at the same point. See for instance stackexchange and the old Q&A

I see. Thanks a lot!
