 Description
-    Potential flow solver.
+    Potential flow solver which solves for the velocity potential
+    from which the flux-field is obtained and velocity field by reconstructing
+    the flux.
 
     \heading Solver details
     The potential flow solution is typically employed to generate initial fields
