New products Chronos
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
VidCAD SQL released for Bricscad V11
The VidCAD SQL Engineering suite of products, previously available for AutoCAD only, has now been released for Bricsys’ Briscad V11. VidCAD SQL is software for designing and documenting complex cabling and electric equipment installations, and when users change cable or equipment information in one drawing, all other drawings and facility data automatically update to refl ect the alterations. All reports are generated inside the software and can be exported to other software or a PDF writer. VidCAD SQL creates intelligent cable labels, including the source and destination info of the equipment and the destination rack. For error checking, it can run reports that search for equipment and cables that are not in the database, ensuring everything is connected and documented.

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 specifi ed and
its material properties and required outputs assigned, Chronos will automatically generate an effi cient mesh for accurate simulation – the
Faraday update
Integrated Engineering Software has updated its Faraday 3D time- harmonic eddy current fi eld solver, fi rst released in 1994. The program provides accurate calculations for optimisation of parameters such as force, torque and power, and the eddy current calculations can be used for determining losses, which in turn can be used for thermal analysis input. Using Boundary Element Method (BEM), Finite Element Method (FEM) or a hybrid of these technologies, design engineers can choose the solver that best suits their models. Boundary elements suit applications requiring the analysis of large open regions and exact modelling of boundaries, while fi nite elements
may be more effi cient for highly non-linear problems or transient analysis.
A key update
has been the multi-threading of the 3D program. It now reduces design time while improving product performance via computer simulations. The speedup for a fi eld simulation process is almost linearly proportional to the number of processors available to the system, and by taking advantage of both the inherent parallelisable property of the BEM, and the advancement in the
computational power
of desktop systems, it achieves excellent parallel scalability. The time dependant eddy current fi eld can also now be simulated directly with the Faraday Transient Solver. Translational and rotational motion- induced eddy current fi elds can be solved with the fi nite element method as well.

software includes a smart mesh generator combined with material identifi cation 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 fi ner grid
in the areas that have fi ne 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.

Bricsys Meeting Point Bricsys has announced Meeting Point, a new online communication hub for end users, application developers, and Bricsys’ .dwg specialists. When a problem occurs with a third-party application running on AutoCAD or Bricscad, end users can post support requests at Bricsys Meeting Point and the system then automatically sends messages to the appropriate application developer.
When developers post their responses, they appear in the users’ My Stuff area with the full history of all support requests. At any time, the end user or the application developer can call on the Bricsys team for help. In the Community Feed section, users can communicate directly with other participants and post short messages about any topic. They can fi ne-tune types of content and areas of interest in Feed Settings. Application developers can post short messages in the Application Feed section that are visible to those users who indicated interest in that application range.
