 The monopole support types available in MFC are listed in table [Monopole supports](#monopole-supports). This includes
 types exclusive to one-, two-, and three-dimensional problems with special souce geometry like transducers as well as coordinate systems such as cylindrical coordinates. The monopole support number (`#`) corresponds to the input value in `input.py` labeled  `Mono(i)%support` where
