+For \esc, the acceleration solution is preferred as it allows the use of matrix
lumping. Lumping or mass lumping as it is sometimes known, is the process of
aggressively approximating the density elements of a mass matrix into the main
-diagonal. The use of Lumping is motivaed by the simplicity of diagonal matrix
+diagonal. The use of Lumping is motivated by the simplicity of diagonal matrix
inversion. As a result, Lumping can significantly reduce the computational
requirements of a problem. Care should be taken however, as this
function can only be used when the $A$, $B$ and $C$ coefficients of the
