This table is meant as a reference and guideline. While we strive to maintain this list regularly, it may be out of date at any given time. If an advertised feature of FlexSim is not listed here, it is generally not subject to limitations by license type.   The Express license type is FlexSim's default, unlicensed state. Downloading and installing FlexSim to a new computer, it will be in Express mode. The other license types require you to obtain a license and apply it to the software. Please refer to FlexSim's End User License Agreement (EULA) for details on allowed uses, restrictions, and other considerations. If you wish to test a particular license type, please contact your local distributor to request a test license.   Please Note: Runtime seats are no longer available for new purchase or renewal but are referenced in this table to support those Runtime licenses still outstanding.   Please Note: Autodesk sells a node-locked subscription license. This is the same as Enterprise in the table below, with some restrictions on moving the license. Please see our article Node-locked license vs Transferable license.       Express Runtime Student Educational Enterprise Use Cases (see EULA) Testing, evaluation, and model viewer only.
