Simulation Tools for Field Solving and Analysis - CAE Tool For Electric Field Analysis - Free Demo Download

INTEGRATED has been the industry leader in Boundary Element Method (BEM) CAE software. BEM not only provides the most accurate numerical field solutions, but also is the method of choice for problems involving large open regions. In contrast, field solvers using the Finite Element Method (FEM) often require artificial "e;smoothing"e; algorithms to average out numerical errors. In addition, artificial boundaries must be used to handle open region problems, and even then, the large meshes required may lead to excessively long solution times.

However, the relative simplicity of implementation of FEM solvers leads to advantages when complex nonlinear or transient analysis is required. FEM very often provides sufficient accuracy for engineering purposes, and many problems are by their nature inherently closed region. Recognizing this, INTEGRATED incorporated FEM solvers to provide users the choice of both methods. A significant side benefit of having both BEM and FEM solvers is ability to check the validity of solutions using two completely different analysis methods.

The most challenging analysis problems occur when both nonlinearities and open regions are present. Here again INTEGRATED takes the lead providing Hybrid field solutions using BEM and FEM simultaneously to exploit the strengths of both methods.

The INTEGRATED Advantage: High Frequency Problems

  1. Solution to an Electromagnetic(EM) model can be obtained in SINGULA is based on the method of moments approach for open region problems and finite element method for closed region problems.
  2. A problem, which is considered as a big one in other techniques, does come under a medium level problem. Hence, a costly parallel processing or distributed processing computing facility is not required for solving high frequency EM problems in SINGULA.
  3. Simultaneous use of lossless and lossy electrical materials in a model is permitted in SINGULA, whereas restrictions in some form exist in the other programs.
  4. Unlike in other programs, the waveguide sources can be used in the open or in the closed region problems.
  5. Radiation patterns of antennas fed by waveguides surrounded by dielectric radomes can accurately be obtained in SINGULA.
  6. Solution convergence with increased mesh density can be established easily in SINGULA. This increases the confidence on the arrived solution.
  7. Some of the results can be coupled to the other INTEGRATED programs for the particle trajectory calculation or thermal analysis
  8. The team of Engineers that are responsible for the development of SINGULA offer the design and technical support to the users of SINGULA throughout.
