sci NEMESIS is an enhancement to the EXODUSII finite element database model used to store and retrieve data for unstructured parallel finite element analyses. NEMESIS adds data structures which facilitate the partitioning of a scalar (standard serial) EXODUSII file onto parallel disk systems found on many parallel computers. Since the NEMESIS application programming interface (API) can be used to append information to an existing EXODUSII database, any existing software that reads EXODUSII files can be used on files which contain NEMESIS information. The NEMESIS information is written and read via C or C++ callable functions which compromise the NEMESIS I API. exodusii
