<font color='black' size='2' face='arial'><font size="2">Dear Sir, I have one question. On the GetDP webpage the example below (in quotes is provided), but I don't see two derivatives in the Formulation Equation section. I see { d v } but where is the rest of the div (grad (v)) portion? Shouldn't there be two derivatives. Thank you.<br>
