         First, a `Curve Loop` gathering the lines representing the boundary of the FEM domain must be created.
         Then, a `Plane Surface` containing the corresponding curve loop must be created.
         Finally, if the plane surface is the first of the .geo file, the physical surface must be created as: 
-        <pre><code>Physical Surface("FEM_domain", x) = {1};.<code><pre> 
+        `Physical Surface("FEM_domain", x) = {1};`,
         where x is the tag of the physical surface.
         Multiple sub domains can be included in the FEM domain. For example, if plane surfaces have been created for
         five sub domains, the physical surface must be created as:
