See a 3D View of your Eagle Cad Layout
On Panel PCB's Like front/back panels. Usability errors may become visible in this simulation. Connector and wiring layout can be better judged on 3D and strain relief and cable management can be planned in power electronics designs.
In sensitive analog circuits; thermal, leakage or guard rings can be inspected. In RF circuits; the shielding, tracks and components can be studied for unwanted coupling, crosstalk or leakage. Finally safety factors also can be judged keeping the enclosure 3d or cabinet in hand.
Now we have low cost 3D CNC prototype makers. Rapid prototyping - additive or laser erosion. You can probably use this as a input for such a machine. Then you can fix it in a cabinet and complete the Mechanical Simulation. This will save wastage of parts, time and pcb's during prototyping.

Fieldbus Foundation - Device Data Networks
'This advanced digital communication solution was designed from the ground-up to support mission-critical control applications where the proper transfer and handling of data is essential. Foundation technology was created to replace incompatible networks and systems with an open, fully integrated architecture for information integration and distributed, real-time control across the enterprise."
High Speed Ethernet (HSE) is ideally suited for use as a control backbone. Running at 100 Mbit/s, the technology is designed for device, subsystem and enterprise integration.
Foundation technology is the world's leading digital protocol for process automation.Industrial network communication system for real-time distributed control. In the Technical Reference area you will find information on Design, installation and operation of Foundation-based plant automation systems....
Foundation Fieldbus H1 uses twisted pair or fiber media to link devices and the controller. Upto 32 Nodes on one port/point.
"Fieldbus is an all digital, two-way multi-drop communications link among intelligent smart field devices and automation systems. FOUNDATION Fieldbus is the Local Area Network (LAN) for instruments used in process automation with built-in capability to distribute the control application across the network."
Here is a Fieldbus Device - Temperature Head Transmitter
Endress + Hauser - TMT85 - The iTEMP® TMT85 is a head transmitter for assembly in a terminal head DIN form B with 2 sensor inputs for resistance thermometers in 2-wire, 3-wire or 4-wire connection, thermocouples, voltage and resistance transmitters.
This is a framework for interactive simulation on OO Java. Consists of a graphical editor, the discrete-event based simulation engine(s), libraries of simulation components, a design and library browser, and tools like waveform viewer and scripting shell..
It is a tool for teaching basic digital systems design, and for research on system-simulation and hardware/software-cosimulation. All simulation models, signal types, and the simulation kernels can be subclassed, so that Hades can be used for other applications as well, not limited to digital electronics.
"The current version of the Hades editor also includes a runtime flag to switch to view-mode: while all of the simulation functions and the option to change component parameters remain active, the editor disables all commands that change the circuit structure. Therefore, view-mode is ideal to let the user play with pre-defined circuits."
