The OmniTrak code for charged particle dynamics can import information on electric and magnetic fields directly from solutions created by our codes HiPhi and Magnum or from field maps. A field map is a text file with a simple and well-documented format that gives values of (Ex,Ey,Ez) or (Bx,By,Bz) on a uniform Cartesian mesh. The field map option makes it relatively easy to incorporate information generated by other field-solution software.
We supply the utility FTabTool (Field Table Tool) with OmniTrak. You can use the program to manipulate field tables (scaling, superposition, …) or to create tables of field values from mathematical functions. This week we made a general overhaul of FTabTool, correcting several bugs. We also standardized the format for writing tables (E13.5) and added the capability to add coordinate translations.
