Which DWSIM version should I use?
Unless you have philosophical or moral objections to using software that isn’t 100% open source, you should download and use the DWSIM Patreon Edition . Why?
DWSIM is a personal, open-source project that I, Daniel Wagner, develop and maintain. It needs to be self-sustaining because of the significant costs involved, and I found a solution in crowdfunding through the patron program. A second, and equally important reason is that people tend not to fully value or appreciate software that is 100% free and open source. Finally, if I distributed every component I develop for DWSIM for free, support would drop drastically, since not everyone takes the initiative to support projects like this. Many simply want everything for free without offering anything in return. That is not sustainable.
In other words, DWSIM’s funding, which remains 100% open source, comes from patron support. I offer them my sincere thanks!
