An extremely useful feature to have if you want to experiment with different finite element discretisations in unstructured geometries. @gnikit, as I have been trying to convey, it is accepted the usefulness and benefits of having heterogenous lists in Fortran code, particularly in “setting up” computations (the so-called preprocessing layers) and consuming and presenting the results (post-processing) from all the number-crunching. Staring Fortran 2003 thru’ the 2008, 2018, 2023 revisions, the language does support such lists. The question is different as noted upthread. --- _[View the full topic](https://fortran-lang.discourse.group/t/heterogeneous-list/4677)._
