Simulators

Turnkey Simulators provide companies access to our knowledge-base in computer modeling and simulations, without involving our engineers in the actual design and optimization project.
Each Simulator is tailor made for a given application, and allows the user to explore a large number of what-if scenarios, both in terms of system geometry as well as operating conditions. In this approach, the client's staff can focus on problem-solving instead of dealing with the nuances and intricacies of general purpose finite element analysis (FEA) and computational fluid dynamics (CFD) packages. Each Simulator is based on rigorous physical modeling, leading-edge computational algorithms, and a graphical user interface.

Our task-specific simulators integrate all of the factors that control the performance of the system into a user-friendly environment:
  • Heat and Mass Transfer
  • Fluid Flow
  • Chemical Reactions
  • Elastic and Plastic Deformations
  • Electromagnetic Couplings
  • Property-Processing Relationships
Our Simulators are used in hardware design, process optimization, and failure analysis. Each simulator is tailor-made to the client's specific configuration and materials application. Yet, it allows the user to change the system geometry as well as the operating conditions.

Examples of turnkey Simulators developed for the semiconductor industry are given below. Simulators.pdf contains a detailed description of these simulators and can be downloaded here.
