One stop simulation tools for all your EMC needs! Modern GUI, advanced geometrical modeling and also easy import from mechanical CAD software, advanced solvers and multitude of postprocessing options. EMC Studio is capable to use the most advanced computational technologies like 64-bit processors and solving very large problems on parallel clusters! We are sure that you have never seen something like this! EMC Studio is a powerful package consisting of several modules serving for the analysis of electromagnetic interference, electromagnetic immunity, and crosstalk in metallic structures with complex electronic components. EMC Studio is ideal for solving EMC problems of large systems like automobiles, aircrafts and ships. EMC Studio elevates the product development process to a level not possible with other CAD products, by seamlessly integrating the model generation process and systems simulation methodology The result is a truly revolutionary hierarchical design approach. This approach improves the effectiveness of the whole simulation process by closing the gap between, until now, separated simulation methods. EMC Studio is based on the fact that EMC problems in large systems like automobiles, aircrafts, ships etc. are mainly determined by: - the large metallic structures - the cable harness - the electronic circuits and the electrical components - the antennas By modelling accurately all the items listed above, and applying suitable calculation methods, a very good and complete prediction of the EMC behaviour is possible. With just field calculation programs it is not possible to handle the complexity of large systems. The generation of an appropriate calculation model is in many cases an unsolvable problem. EMC Studio closes the gaps, and generates complicated calculation models for large systems by using sophisticated hybrid methods. A few features:
Modules EMC Studio consist of several modules that work together in an EMC design environment: - EMC Designer is the main control board from where you can launch various applications and analyze the results. The EMC Designer is a graphical user interface that allows you to model your calculation tasks in a very sophisticated and intuitive way, to define the parameters for the solver modules and to visualize the results. With EMC Designer you can either generate the geometry model based on primitives like plates, triangles, cylinders and spheres or you can import files from other meshing program like e.g. ANSA, MEDINA, FEMAP or PATRAN in NASTRAN or PATRAN format. Complicated cable harnesses can be modeled by hand very easily with a few mouse clicks or imported via the XML or STEP AP 212 data formats. - Graph Studio is a convenient tool to visualize, compare and present your results. Graph Studio is fully integrated into the EMC Designer. This gives very easy access to data from last and data from former simulations. Arbitrary styled graphs can be displayed and modified. - ReMesh a mesh generator that can help generate a coarser mesh for complicated geometries imported from mechanical CAD. Accurate calculations require specially adapted models, ReMesh gives the possibility to refine and adjust the mesh in critical regions with just a few mouse clicks. - TriD a full-wave electromagnetic field solver based on 3D MOM using triangular meshing of the surfaces. Since 3D electromagnetic field calculations are very compute intensive, TriD has a parallel version also for faster execution. - Static3D is a static field solver used to calculate the capacitance/ inductance matrices of complicated 3-dimensional metallic structures - Static2D is a static field solver used to calculate the parameters of the transmission lines included in design (capacitance and inductance per unit length) - EMSpice a Spice type circuit simulator that includes: AC Small-Signal Analysis and Transient Analysis - Low-Frequency Engine gives an unbeatable flexibility, speed and accuracy when calculating low frequency problems in frequency or time domain. The frequency limit depends mainly on the extension of the analyzed geometry. An average automobile structure can be calculated with good accuracy up to 2 MHz. This Engine uses the Static3D solver and EMSpice. Within the EMC Studio environment the complete calculation chain is performed with minimal user intervention. - Cross-Talk-Engine a module specialized in calculation of the crosstalk between arbitrary cable structures. Ideal, lossy, nonuniform, shielded cables as well as twisted wire pairs can be analyzed. - TL2Field Engine allows the inclusion of the radiation from arbitrary cable structures (terminated with lumped linear, nonlinear, passive or active circuits) into the full-wave EM field solver. - Field2TL Engine is a module that allows the fast computation of the coupling of EM fields to complex multi conductor transmission line structures. Insulation and small spacings can be included as well as arbitrary terminations (linear, nonlinear, passive or active circuits). This engine represents an important extension to conventional EM-field solvers. -Virtual Bench is another outstanding feature of EMC Studio. It allows to emulate inside the design environment the actual bench testing of electronic components as done in the real development process. With Virtual Bench the user can easily check out if a component fulfills the given specifications and standards. Furthermore the electronic components can be directly checked in the planed final environment like e.g. an automobile. The operation of Virtual Bench is similar to real testing and measurements. The user just needs to generate a model for his electronic components and the virtual testing as well as measurements can start. EMC test like: TEM test chamber, EMC Stripline, virtual antennas and the Bulk Current Injection (BCI) are implemented in the Virtual Bench. Preprocessor You can define your own 3D structures in EMC Studio, however you can also import geometrical models from mechanical CAD software. There are predefined shapes like lines and curves, circular and elliptical cylinders, and you can define arbitrary polygonal surfaces that can be joined in a 3D model. Objects can be inserted totally or partially into other objects, creating various structures. All this can be done in the graphical interface or can be done in a text file that describes the structure. All parameters, dimensions and material constants can be defined as variables. Various excitation sources can be included like: incident plane waves, voltage sources, current sources, impressed currents, electric and magnetic dipoles as well as arbitrary combinations of them. The sources can operate in frequency or time domain. Solvers There are four different solvers included. A 2D and 3D electrostatic solver, a 3D full-wave EM solver (MOM) and a Spice type circuit solver. EMC Studio uses various Hybrid Approaches by merging of different methods, this way combines their advantages, and eliminates their drawbacks: - 3D EM programs + Transmission Line calculation programs. Fields are calculated without considering the presence of wires by 3D electromagnetic solvers and then the field results are use as transmission line excitation sources - Transmission Line calculation program + Electric Circuit calculation programs. Transmission line systems are subdivided onto small segments and each segment is modeled as electric circuit with lumped parameters. In this approach the load attachments (including non-linear ones) can be modeled with circuit tools (SPICE) Postprocessor EMC Studio and Graph Studio calculate and represent in 3D the current, electric, and magnetic field distributions, they plot the frequency dependence of impedances and S parameters, frequency and time domain probe voltages, radiation patterns, etc. Results can also be visualised in Matlab for more flexibility.
