As starting point, if you like to use tikz
package for drawing, can serve the following (pseudo)code:
\documentclass[tikz, border=1ex]{standalone}
\begin{document}
\begin{tikzpicture}
\draw[draw=green, very thick, rounded corners, fill=gray]
(<coordinate 1>) -- (<coordinate 2>) -- %and so on
(<coordinate k>) node[above=3mm] {$\Omega$} -- %and so on
(<coordinate n) -- cycle;
\draw[draw=red, very thick, rounded corners, fill=white]
(<coordinate 1>) -- (<coordinate 2>) -- %and so on
(<coordinate j>) node[above=3mm] {$\Gamma_u$} -- %and so on
(<coordinate n) -- cycle;
\end{tikzpicture}
\end{document}
Selection of coordinates is left to you. Also to which one you wish to associate node with $\Gamma_m$.
(0,0) -- (2,0.5) --
etc. With this and reading TikZ manual or searching for example texample.net you will learn, how to draw similar pictures yourself. Please, edit your question and add it what you try to do with my code and where you stuck
