     dynamic_viscosity(u, equations)
 
-    Wrapper for the dynamic viscosity that calls
-    `dynamic_viscosity(u, equations.mu, equations)` which dispatches on the type of 
-    `equations.mu`. 
-    For constant `equations.mu`, i.e., `equations.mu` is of `Real`-type it is returned directly.
-    In the opposite case, `equations.mu` is assumed to be a function with arguments
-    `u` and `equations` and is called with these arguments.
