I need some help in understanding formulations. How does the following line: "Galerkin { [ epsr[]*Dof{d v} , {d v} ] ; In Vol; Jacobian Vol ; Integration Int ; }" translate into "div epsr[] grad v=0". Is the grad operation implicit in "Dof{d v}"? Where is the div operation specified? These are probably very simply questions, maybe someone can enlighten me. Tammo
