ANSYS Parametric Design Language (APDL) is a powerful structured scripting language used to interact with the ANSYS Mechanical solver. Mechanical APDL (MAPDL), a finite element analysis program, is driven by APDL. APDL and MAPDL can be used for many tasks, ranging...
Read MoreSubmodeling, as the name suggests, is the modeling of a portion of a global model to capture the effects of refined mesh in a smaller model. This is done to avoid having the whole assembly meshed with fine elements. ANSYS Mechanical...
