Electric field solver speeds up product development
04 February 2009
Integrated Engineering Software, a leading developer of hybrid simulation tools for electromagnetic, thermal and structural design has launched an enhanced version of its COULOMB 3D electric field solver software. Fast and accurate, COULOMB's calculations include electric field strength, transmission line parameters and capacitance. It is suitable for applications such as high voltage shielding, transformers, insulators and bushings, transmission lines and lightning arresters.
Powerful parametric solvers allow designers to automatically vary and experiment with geometry, materials and sources – reducing the tedious, repetitive task of fine–tuning multiple design parameters. Version 7.0 of the software includes features such as self adaptive 3D Finite Element Method and a better use of memory. The self-adaptive 3D FEM feature has been significantly enhanced, it is now quicker to converge with less iterations. The only practical limitation for this feature is the amount of RAM available on the workstation. The program can now solve larger FEM problems up to 10 times faster than previously.
Other new features include the commands for Geometry Define Surfaces On Plane and Define Planar Surface. These commands will help the user to define surfaces on a plane during geometry construction. There is also a new Scale Periodic Length for the Periodic model when the Parametric Geometry Scale is used, giving the user the option to scale the periodic length along with the parametric geometry.
A new variable ‘L’ (which stands for ‘length’) has been added to the command line parser. This will allow users to type ‘L’ to substitute the length for the segment as an input for the next command prompt. The rotate, copy and repeat functions have been sped up in 3D by approximately four times, improving the amount of time the designer needs to spend in the modeling process. There is also new support available to enable or disable visibility for FEM bounding box, making the BEM 3D bounding box transparent. In addition, new hot keys will mean the user need not get out of a command in order to change the work plane depth.
