Define your modeling needs and objectives (back to the top)
Defining your needs and objectives will greatly assist in the software evaluation process.
Define the types of problems that must be modeled (back to the top)
Understanding the types of problems that must be modeled is critical in the software evaluation process.
Every software package has its strengths and weaknesses. Many codes are specialized or tailored for specific applications while others are very general and suited to a wide variety of problems. Here are some important considerations to take into account,
Determine, if possible, the most time-consuming modeling tasks (back to the top)
Determining the most time-consuming modeling tasks will help you set proper priorities for various software features, hardware choices, and license costs. Quite frequently users underestimate the amount of time it takes to create and validate a model. Execution time, even if it takes many hours, can be easily eclipsed by many days or even weeks of geometry creation, model creation, and model validation. On the other hand, sometimes a single, relatively simple model can be followed by weeks of parametric studies, so computer execution times become very critical. The three main tasks in modeling and simulation are:
Define budgets (back to the top)
Depending on your requirements, in-house modeling can demand significant capital investment in hardware and software along with ongoing need for staff funding and software license maintenance.
Identify available or required staffing resources (back to the top)
Availability of qualified staff is imperative to the success of in-house modeling capabilities. Understanding of both electromagnetics and numerical techniques is necessary, and the learning curve for software usage can be steep and lengthy. If new staff must be hired, it can take a significant amount of time to recruit qualified individuals.
Take a little time to research and understand CEM methods. Researching the types of available methods can make it easier to understand the capabilities and the limitations of electromagnetic simulation software.
Appropriate choice of CEM software will make your modeling more efficient and your simulations more accurate. It will also keep you from spending unnecessarily on features and capabilities you may not need.

Understand license types and prices (back to the top)
Licensing practices vary widely. If you want to avoid expensive surprises after you make a commitment to a particular vendor, make sure you thoroughly understand the vendor's licensing options. Here is a list of common licensing practices:
License management issues can be important as implementation vary. Customer service considerations are also important, for example, the vendor's ability and willingness to transfer license between machines.
Select available and required computer hardware (back to the top)
Here are some factors to consider when selecting hardware:
Investigate training options (back to the top)
Training can be very important in mitigating steep learning curves that are associated with establishing CEM modeling capabilities. Many companies offer such training options as instructor-lead courses (in-person or online), free workshops, online video courses, self-paced training exercises and modeling examples. For instructor-led courses it is worth while learning about course availability, frequency, duration, variety (short and long, introductory and in-depth, application-related, etc.), and, of course, cost.
