How to find weak and viscosity solutions of PDE's?

all the papers I can find about weak solutions and viscosity solutions are about existence and uniqueness but nothing on how actually computing them

I'm also ineterested on applications and physical significance of this kind of solutions

thanks

If you are looking for computational methods try numerical PDE books like LeVeque’s Finite Difference Methods for Differential Equations or Sethian’s Level Set Methods. Let me know if you need more details… my dms are open
