The 3D Space Charge module uses code that is optimized for the shared memory architecture of standard PCs and workstations with multi-core processors. Although the speed benefit of parallel processing depends on model complexity, highly iterative and computationally-intensive analysis tasks can be greatly accelerated by the technique. By parallelizing the solve process, including the existing efficient particle tracking algorithms, the parallel processing version of the 3D Space Charge module can shorten simulation run-times significantly. Application areas include X-ray machines, electron microscopes, field emission displays, mass spectrometers, electron beam lithography equipment, ion-beam sources and magnetron sputter coaters. The space charge solver fully integrates with Opera-3d’s Modeler and Post-Processor, giving access to Opera’s full range of model creation and results analysis tools.
