 They represent single-cell setups, i.e. they solve the population balance
 equation without spatial transport. The setups already represent the
 inhomogeneous case, i.e. the populationBalance is split over multiple
-velocityGroups. This can help to identify wether the populationBalance-induced
+velocityGroups. This can help to identify whether the populationBalance-induced
 mass transfer terms are handled correctly. The cases can also be used to study
 the influence of certain parameters on the form of the size distribution, before
 running a simulation with spatial transport. Further test cases are contained in
