Global equation or constraint

Please login with a confirmed email address before reporting spam

Hi all, I am using weak-form PDE interface to do multi-variable physics modeling. Say, we have three variables u, v, w. After i input the weak form equations, i want to add a global constraint, e.g. 1=u^2+v^2+w^2. How can i do it?
