Each version number of FDS contains three integers, for example, FDS 5.1.3. The number 5 is the major release; the number 1 is the minor release; the number 3 is the maintenance release. This page provides a summary of the minor releases starting with the major release, FDS 5. It also provides details of the changes made between maintenance releases. Changes in the maintenance release only involve bug fixes, whereas changes to the minor release involve changes in program functionality. It is recommended that you continually update maintenance releases, but update the minor release only with the start of new projects because some results might change.

Summary of FDS Minor Releases

FDS 5.1

In simulations involving multiple meshes, FDS no longer allows the meshes to be arbitrarily connected. Starting with version 5.1, mesh resolution can only increase or decrease in integer increments. This change in functionality means that some input files that ran previously will no longer run.

Details of FDS Maintenance Releases

The following text is the change log history for each release of FDS_5.
