Integrated Engineering Software
A new time domain solver and high frequency tool for modelling and simulating 3D RF and microwave applications has been released by Integrated Engineering Software. The software, named Chronos, addresses the modelling and simulation of RF applications and antennas in terms of speed, required memory and accuracy. Closely related to Singula, the company’s 3D high-frequency time harmonic electromagnetic analysis software, it will provide designers with techniques such as Finite Difference Time Domain, Moment of Methods (MoM), and the Finite Element Method (FEM).
The interface enables design engineers to model the geometry and assign physical properties, providing fast and accurate results in both time and frequency domains. Time domain results can be transformed and displayed with different parameters in the frequency domain using the automatic post-processing tools. The move from Frequency Domain techniques into the Finite Difference Time-Domain (FDTD), combined with the parallelisation of the program, brings time savings.
After the geometry is specified and its material properties and required outputs assigned, Chronos will automatically generate an efficient mesh for accurate simulation – the software includes a smart mesh generator combined with material identification code. This code has the ability to recognise all the details of any structure and decide how to distribute the mesh sizes based on the accuracy requirements of the time domain solver. The mesh is generated by placing a finer grid in the areas that have fine features and then increasing and decreasing the cell sizes gradually between the different regions whilst maintaining the accuracy requirements for the time domain solver. The mesh distribution can be generated manually or automatically.
Chronos is compatible with all major CAD programmes such as Tecplot, Autodesk, SolidEdge and Solidworks.
