System Deflation

Dear bempp-cl team,

When solving a problem for the electric potential I have a system that is in principle singular.
My system is (0.5M+DLP)\phi = F, where M is the identity operator (or mass matrix), DLP is the double layer boundary operator, \phi is the potential that I solve for and F is a load function.
I would like to apply deflation to move the eigenvalue that is zero to make the problem solvable and improve the system condition.
Is deflation or anything similar implemented in Bempp?

Kind regards,

Hi Peter,

that is something you would need to do manually. We do not have corresponding functions built-in.
Best wishes
