Models can be composed of different units (models at finer granularity) linked to achieving a specific goal; for this reason they can be also called modeling solutions. More generally, modeling and simulation is a key enabler for systems engineering activities as the system representation in a computer readable (and possibly executable) model ...
A virtual engineering environment provides a user-centered, first-person perspective that enables users to interact with an engineered system naturally and provides users with a wide range of accessible tools. This requires an engineering model that includes the geometry, physics, and any quantitative or qualitative data from the real system.
The split between analysis and design models: The analysis domain expresses precisely what the system must do, the design domain is a model of how the Shlaer–Mellor virtual machine operates for a particular hardware and software platform. These models are disjoint, the only connection being the notation used to express the models.
There are various types of EDA tool used for ESL design. The key component is the Virtual Platform which is essentially a simulator. The Virtual Platform most commonly supports Transaction-level modeling (TLM), where operations of one component on another are modelled with a simple method call between the objects modelling each component.

The subsequent design phase refines the analysis model and makes the needed technology and other implementation choices. In object-oriented design the emphasis is on describing the various objects, their data, behavior, and interactions. The design model should have all the details required so that programmers can implement the design in code. [4]
The MDE approach is meant to increase productivity by maximizing compatibility between systems (via reuse of standardized models), simplifying the process of design (via models of recurring design patterns in the application domain), and promoting communication between individuals and teams working on the system (via a standardization of the terminology and the best practices used in the ...
There are a number of Free and Open-Source Software tools that support Computational Engineering. OpenSCAD was released in 2010 and allows the scripted generation of CAD models, which can form the basis for Computational Engineering Models. CadQuery uses Python to generate CAD models and is based on the OpenCascade framework.
