MDL, or Model Development Language, is a programming language designed for creating and managing models in various fields, including engineering and science. It allows users to define complex systems and simulate their behavior, making it easier to analyze and optimize designs. In addition to its modeling capabilities, MDL is often used in conjunction with software tools that support simulation and analysis. This integration helps professionals in industries such as aerospace, automotive, and manufacturing to visualize and test their ideas before implementation, ultimately saving time and resources.
