New question #145534 on DOLFIN:
https://answers.launchpad.net/dolfin/+question/145534

Hi all,

I am using the dolfin to solve a PDE problem by finite element method. However, I met a problem when I try to define the linear form L(v) of right hand side. Suppose the PDE is:

F(x) = f.

What should I do if the f is a Dirac Delta function. How to define it in ufl?
Anybody met and solved the similar problems before?
Thank you for attention and kind help.

Yi
