Simulation and Modeling

There are situations when direct measurement of field strengths, no matter how thoroughly or competently performed, are inadequate to the analytical requirements. In other cases, direct measurements are impossible – the facilities do not yet exist. At such times, analysis by computer model is appropriate.

Common Uses of 2-D and 3-D Computer Simulations Include:

FACILITY SITE PLAN AND LOCATION:  There are many external electromagnetic influences that act upon a proposed facility. In some cases the external electromagnetic influences are so great that the placement of a facility within a parcel of land becomes relevant. This is true especially in urban environments where established rights-of-way for power, telecom, and transportation are well-established. The proper geographic placement and planning of a facilities location can impact the cost and performance of activities within. Getting this right can directly influence the use and value of a facility to its intended activity. FMS will help you get it right by providing electromagnetic simulations and visualization aids.

TRANSPORTATION INFRASTRUCTURE PATH OPTIMIZATION:  The use of mass transit options such as light rail is growing. New transport lines and expansions of existing systems are being widely proposed. These projects, while positive for communities, can negatively impact the electromagnetic environment of existing or planned facilities. FMS is expert in this domain. Often small changes in the planning of light-rail can preserve the medical or research electromagnetic environment that is critical to the operation of advanced research and medicine. FMS identifies these issues ahead of time with simulations and helps provide alternatives that preserve technology investments in communities that are newly served by mass transit options.

LOW-EMF BUILDING DESIGN:  New buildings – whether for Research, Medicine, or Commercial Enterprise are increasingly infused with technology. This technology can be a source of electromagnetic influence or be affected by the electromagnetic environment. Energy saving technologies such as Variable Frequency Drives (VFD’s) can make facilities more efficient, but they can also influence the operational effectiveness of research tools and medical technologies. Trends in Cogeneration and higher power densities in facilities also create challenges in achieving a low EMF facility. FMS has unmatched assessment capabilities to model and provide options that cost-effectively meet low EMF criteria in buildings. A computer simulation of the likely fields from an electrical component or distribution facility can guide the space planning function or can suggest changes in the design. The improvement to understanding the long-term utility of a facility to house low EMF functions is valuable.

PEER REVIEW-VALUE ENGINEERING: FMS often will be called upon to assess facility electromagnetic environments as designed by others. This peer-review can help provide fresh insight and scrutiny on requirements for electromagnetic shielding. Often this sort of Value Engineering approach can lower facility costs and allow budgets to be applied to core facility missions. Our 3D and BIM-based simulation methods provide unprecedented visualization of the EM environment allowing for the optimization of electromagnetic field mitigation measures that meets specific facility requirements.
