[1][2] ASCEND is an acronym which stands for Advanced System for Computations in Engineering Design.
Its main uses have been in the field of chemical process modelling although its capabilities are general.
So domain experts (people writing the models) and computational engineers (people writing the solver code) can work separately in developing ASCEND.
Together with a number of other early modelling tools, its architecture helped to inspire newer languages such as Modelica.
