Hi,
I used a conductive media DC to find the external electric field (E) in my computational domain; Now, I would like to compute the Laplacian of E.
I really appriciate it if anyone tell me how can compute any non-defined operators in Comsol. For example, how can I compute the Laplacian or grdient of the obtained external electrc field (E) by Comsol in one specific subdomain.

Thanks in advance!
