EwE6 beta test program

The Ecopath development team would like you to participate in the beta testing program. For four week periods, once or twice per year, you will have the opportunity to use the next oncoming release of the EwE software to help finding any remaining bugs. You will work in close contact with the EwE development team, and we will be dedicated to address any issues that you may find with highest priority to ensure a solid release of EwE.

If you are interested in participating in the Beta programs please send us an email.

The EwE6 source code is freely available upon request. This section aims to provide you with resources that would help you develop your own code using the EwE6 source code.
