solver). The traction vector is discontinuous and I do not have a function
to describe it.

Hello everyone,
I would like to apply a traction boundary condition on the surface of a
cantilever beam. Suppose I have a vector named
*traction[dof_handler.n_dofs()**], *which gives the various traction on
each dof. I implemented the boundary condition as follows:
for ( unsigned

Dear Dr. Bangerth,
Thank you for the quick reply! After installing LAPACK, the code works!
Thanks,
