While APDL was the standard method of setting up models for many years, it required engineers to be trained on the myriad commands available and was enhanced with a more intuitive graphical user interface (GUI) in the early 2000s. Ansys was the first commercial simulation tool provider to offer users a versatile programming language to create parametric models for systemic analyses.ĪPDL has been around since the 1980s, initially developed by John Swanson to replace punch card instructions in mainframe computers with a simpler, easy-to-use language for personal computers. APDL and MAPDL can be used for many tasks, ranging from creating geometries for analysis to setting up sophisticated solver settings for highly complex analyses. Mechanical APDL (MAPDL), a finite element analysis program, is driven by APDL. Ansys Parametric Design Language (APDL) is a powerful structured scripting language used to interact with the Ansys Mechanical solver.
