Get the software
Two ways to try CPO — a free edition with no time limit, or a 15-day evaluation with every option unlocked. Both are 64-bit and install in minutes.
Free · No time limit
CPO2D + CPO3D · users guide · on-line help · nearly 200 benchmark and example data files
Perfect for students and for exploring how the programs work. Limited to 1,500 segments in CPO2D and 3,000 in CPO3D, and the following advanced options are not included:
Evaluation · 15 days · Every option
CPO2DS + CPO3DS · users guide · on-line help · nearly 200 benchmark and example data files
The full software, including space charge, cathodes and every advanced option — up to 5,000 segments in CPO2DS and 12,000 in CPO3DS, more than enough for any problem.
Near those segment limits? You're probably not taking advantage of the Boundary Element Method — reworking the problem usually improves calculation times too.
We no longer offer 32-bit builds due to the memory limitations of 32-bit processes — the free 64-bit edition should be sufficient for testing older machines.
