Download the latest build of the SpeedCHEM library and standalone SpeedCHEM constant-volume application.
Remember that by downloading SpeedCHEM you implicitly accept the terms and conditions contained in the License, and agree to the requirement of properly acknowledging the SpeedCHEM references listed in the documentation page in all the appropriate places.
The download is currently password-protected, in an attempt to keep a list of the active users and share updates and fixes among them; please write me an email to request it. I am working to reduce the hassle and provide a simple "user registration" form. Apologies for the inconvenience.
