CHEMKIN FAQs


These questions and answers are intended to clarify the intellectual property position of Sandia and Reaction Design, and to provide guidance on the use and distribution of CHEMKIN™.

Q.

How can I acquire CHEMKIN software?

A.

CHEMKIN is available through a San Diego company called Reaction Design, Inc. In February 1997, Sandia contracted with Reaction Design to become the exclusive worldwide CHEMKIN distributor. Under this license agreement, Sandia and Reaction Design cooperate on the continuing development of the CHEMKIN software.


Q.

In the past, wasn't CHEMKIN available for free?

A.

Beginning in the late 1970s, Sandia National Laboratories developed CHEMKIN and later CHEMKIN II. Sandia distributed the code widely to collaborators around the world. Sandia has always maintained copyright and ownership of the CHEMKIN programs and the CHEMKIN name. Sandia never placed CHEMKIN in the public domain and has never authorized recipients to re-distribute CHEMKIN either as a software product or as modified and incorporated into subsequently developed software. Until 1997, the only organizations authorized to distribute versions of CHEMKIN were Sandia and Department of Energy Office of Scientific and Technical Information (OSTI).


Q.

My organization received a free version of CHEMKIN in the 1980s from Sandia. Can we continue to use it?

A.

Parties who received versions of CHEMKIN directly from Sandia in the 1980s and early 1990s or purchased it from the Department of Energy Office of Scientific and Technical Information (OSTI) have a right to continue to use and modify that software, and to publish the results. However, Sandia and OSTI did not grant permission to distribute these early versions of CHEMKIN either in part or in its entirety, or as modified or embedded in third-party software.


Q.

What if I have an unauthorized copy of CHEMKIN?

A.

For parties who may have received CHEMKIN through unauthorized distribution and are currently using CHEMKIN, we request you contact Reaction Design at chemkin@reactiondesign.com to obtain the latest information about current CHEMKIN products and extensive CHEMKIN support services.


Q.

In view of the change in how CHEMKIN is distributed, and the initiation of a fee-based license program, how are Sandia and Reaction Design addressing the needs of the scientific community?

A.

Sandia and Reaction Design acknowledge that there has been some confusion over the intellectual property status of CHEMKIN with regard to early versions that Sandia National Laboratories delivered to collaborators in the 1980s and early 1990s. Sandia and Reaction Design encourage and support the widespread use of CHEMKIN in the scientific community. Included in the license agreement with Reaction Design are measures to support this research community, including:

  • The right for Sandia to designate active collaborators who are eligible to receive current CHEMKIN versions at no charge
  • Substantially discounted license fees from commercial rates for academic users
  • Establishing a CHEMKIN users' public Web site to facilitate the free exchange of information and problem solving experience among users
  • Providing access for researchers who wish to modify the current commercial code and are willing to have their improvements incorporated into future CHEMKIN releases
  • Holding biennial workshops to encourage feedback from users on the future direction of CHEMKIN in conjunction with International Combustion Institute meetings

Q.

I have CHEMKIN II as a result of a collaboration with Sandia. Should I upgrade to the latest version of CHEMKIN?

A.

There has been no further development of CHEMKIN II since 1995. Since that date there has been substantial modification and enhancement.

Parties still using CHEMKIN II will discover considerable benefit by upgrading to this more advanced version. Those whose special applications require capabilities not yet incorporated in the current version are encouraged to request source code directly from Reaction Design to facilitate such modification under the Reaction Design Collaborative Development agreement.

For more information on the latest version of CHEMKIN visit http://www.reactiondesign.com or email Reaction Design at chemkin@reactiondesign.com.


Q.

What is the proper use of the CHEMKIN name?

A.

The CHEMKIN name is a trademark owned by Sandia National Laboratories and needs to be expressed as CHEMKIN™. The trademark name may be used in scientific papers or as a literature citation. All other use of the trademark name "CHEMKIN" requires permission from either Sandia or its exclusive CHEMKIN licensee, Reaction Design.
