I want to write a symbol like the one shown in the following image

but I can't make it work. I tried:

$$ underbar{nabla} $$

but it didn't work (I think the reason for this is that the input for the underbar command should be only text.

How can I make this work ?

underline

  Why are you using the text-mode command underbar instead of the math-mode command underline?

  underline is the primitive (and math mode), underbar is a latex text mode version defined essentially as defhbar#1{underline{hbox{#1}} so nesting that in another hbox layer and another math group to get back to math mode is not the most direct route.
