Free 32-bit versions

Introduced in 2023, the freely available 32-bit versions of cpo2ds and cpo3ds have some limitations.  The maximum numbers of segments are 1500 and 3000 for cpo2ds and cpo3ds respectively and the following options are not available: scattering, stochastic, user cathodes, dielectrics, field import.

The full 15-day 64-bit evaluation version is still available and the 'perpetual' 64-bit software can still be purchased.
