This download includes CPO3DS (64-bit), CPO2DS (64-bit), users guide, on-line help and nearly 200 benchmark and example data files.

The maximum number of segments is 5000 for CPO2DS and 12000 for CPO3DS. This is more than enough segments for any problem.

If you are near this number of segments then you are probably not taking advantage of the Boundary Element Method and could easily improve calculation times by reworking your problem.

We no longer offer a 32-bit build of CPO3DS due to the memory limitations of 32-bit processes. The free 64-bit edition below should be sufficient for testing.

This download includes CPO3D (64-bit), CPO2D (64-bit), users guide, on-line help and nearly 200 benchmark and example data files. The free version has a limitation of 1500 segments for CPO2D and 3000 for CPO3D.

Please note that the free version does not include the following advanced features. If you need these options, you can download a 15-day evaluation of the 64-bit version before deciding whether to purchase the full 64-bit edition of the CPO software:

• Large numbers of segments
• Scattering
• User cathode
• Dielectric
• Field import
