Any software (EDA tool) that can numerically simulate electrodynamics system? For example in micro scale particles that accelerate in an accelerator or in larger scale, charged particles and electron microscopes?
OPERA 3D with following modules TOSCA - electrostatic, magnetostatic, SCALA- space charge and interaction of charged particle with EM fields, SOPRANO- resonant cavities and waveguides, TEMPO- thermal analysis, ELECTRA, CARMEN- for rotating machines etc.
CST - CST MWS, CST PS, CST EMS,
Ansys- HFSS, Maxwell
COMSOL Multiphysics with specific modules for each application
Many of us write our own codes to deal with specific problems. Giovanni and Nitin have listed many of the good packages available. Can you be more specific about your needs? There is a wide range of operating parameters in just the two examples you mention: particle accelerators and electron microscopes, and there is not one code that can deal with all the important physics for all cases. Many assumptions need to be made for most simulations to be tractable in a finite time with finite memory.
@nitin, would you please rank the software you have listed? They seems too many, so may tell which one is the most proper simulator for electron beamed application.
