ACS SASSI Submodeler is the current graphical user interface for the simulation modules in as of the ACS SASSI V3.0.0 installation kit.

When the user Opens Submodeler the interface will look very similar to PREP interface. Unlike Prep, on entry to the Submodeler there is an empty model ready to be used without requiring the use of the new Menu option to create or load a model the user should consult the Getting Started topic. When the model is ready for simulation the user can launch the required Modules directly from the Submodeler without having to go to Main. The File conversion processes from File Converter has been expanded and allows the user to directly input model data into Submodeler without need to write a pre first.

The Submodeler shares no code with PREP, MAIN or the File Converter which it replaces. Difference between the Prep and Submodeler interfaces and functionality were kept as minimal as possible to help users transition to the new version of ACS-SASSI.

A user opening the Submodeler on there computer for the first time will see a few lines of text in the command window in the warning color [yellow (by default)] before any commands are entered. The warnings are triggered because Submodeler did not find an initialization options files or the Submodeler databases. The submodeler will then attempt create and store 3 xml files in the users account profile. (Location varies by Operating System) These files are called SASSIini.xml, SASSIdb.xml and SASSIani.xml. If there are errors [red text (by default)] in this text or the yellow text reappears on subsequent uses of the Submodeler the user should contact there system administrator about there user account settings.

Note: The files are local to the user account not computer if a user has multiple account the user will see these messages on the first usage in each account.

The first new capability of the Submodeler is the ability to open and use multiple models at the same time. Submodeler has a state machine protocol for accessing and creating new models. All commands and user interface options affect the current active model. User should be familiar with this concept because it is the same way that the GROUP and Element commands worked in Prep and continue to work in Submodeler. All models in the Submodeler are referenced by positive integer number with the default model (empty model on opening) number being 0. To access any model the user must use the ACTM command

The size limitations on models has not changed in the latest version of SASSI. It was found that many functions of Prep are very inefficient when dealing with models that are close to the limit of SASSI. First, when Loading an pre only the comments in the file and errors encounter are reported to the command history. The command entry and acceptance shown in the command history during input dramatically slows down the input process and with volume of commands in a larger model will overwrite the error. This sped input of a pre file that take 15 minutes in PREP to under a minute in the Submodeler. The Submodeler uses OpenGL 4.0 for graphics which allow for better display of large models. Finally the internal storage format of data in the Submodeler was changed to decrease the memory needed to store each model.

The Submodeler name implies that a user may take a piece of one model and use that as a separate model this is covered in the Submodeling example.

The Submodeler has the ability to Merge two models in memory into a single model. The Process is described in the Merge topic.

There are many repetitive task that cannot be covered by a simple command. Submodeler introduces Macros and Loops to help the user to complete these repetitive task with less chance of errors arising from copy and paste problems.
