The results of calculations obtained from DWSIM yield approximate results, which will not always be suitable for every application. The software is designed for use by trained professional personnel and is not a substitute for sound professional judgment. It is the sole responsibility of the user to validate the data presented by DWSIM and to determine whether the results of this program are accurate and suitable for any specific purpose.

Support the Project

If DWSIM is or was useful to you in any way, please consider making a donation using PayPal or through the download system when you download an installation package.

When you donate to DWSIM project, you donate directly to me, Daniel Wagner Oliveira de Medeiros, the main developer, site mantainer, project manager, etc...

Donations made through the download system will be transferred to PayPal first, then to my bank account. Donations made through the PayPal button are transferred to my bank account. Almost 15% of what you donate is "lost" in transaction fees and currency conversion rates.

Donations are for me as an individual and thus each donation supports everything I do, i.e. they help me pay my bills at the end of the month among other stuff. I also donate to some charity campaigns but these donations are personal, they have nothing to to with DWSIM and thus do not depend on the donations I receive from it.
