Changes in program capabilities usually occur when I am involved in a consulting project. While working intensively with a program, I invariably find that there is a missing feature or that an existing feature is irritating. Both aspects apply to the CircBeam and RectBeam tools of OmniTrak.
To review, the CircBeam tool creates a particle file (PRT) [...]
In the beginning, you either had an IBM PC or a clone. In either case, the operating system was MSDOS which was supplied with no utilities whatever. Organizing files with DOS commands was time-consuming and frustrating. It was a joy when the first two-window file management programs were released. The best-known example was Norton Commander, although [...]
The magnetic force on a vector current element dl carrying current I in a magnetic field with flux density B is
dF = I dl × B (1)
In Magnum applied currents are represented by a collection of filamentary elements, so you might think that it would be straightforward to implement automatic routines to find forces on drive coils. [...]
GamBet, our Monte Carlo code for X-ray science and technology, has always been ahead of competitors with regard to special features (I’ll mention some later). In the past other packages may have had more raw computing power. We advanced the number-crunching capability of GamBet last year when we introduced parallel processing (http://fieldp.com/myblog/2011/multicore-gambet/). With this feature, GamBet [...]
Field Precision programs are optimized for the latest generation of multi-core or multi-processor PCs. The 64-bit major solution programs (HiPhi, Magnum, GamBet,…) feature true parallel operation. The time-intensive subroutines have been coded in OpenMP, giving significant improvements in speed (see magnum-in-parallel or multicore-gambet). A second feature is the capability to run multiple independent calculations simultaneously. All [...]
