Pack and Unpack

Pack

Model Pack

The aim of the Pack/Unpack facility is to provide an easy mechanism to exchange models (.ame files) between users. Another use is to provide a convenient archive mechanism for models.

It is necessary to have a special nomenclature for Pack and Unpack. Five terms are now introduced.

1. Auxiliary files: It is possible to send the .ame files directly (by e-mail, for example). However, this often leads to failures because certain auxiliary files are missing. Here are some examples of auxiliary files:

Tables (i.e. data files) read by submodels

Images stored in files

User (as distinct from Simcenter Amesim) submodels and associated .spe, .c, .f, .html, .obj (or .o)

User supercomponents and associated .spe, .sub and .html files

User customized objects and associated .spe, .sub and .html files

submodels.index, AME.make files

Files defining user categories and icons contained in those categories

Libraries (.lib or .a) and associated source and makefiles

2. Simcenter Amesim nodes: These are the parent folders or directories where submodels and supercomponents are stored. If a submodel is stored in the folder /home/user/simulation/valves/submodels then /home/user/simulation/valves is a Simcenter Amesim node. All Simcenter Amesim nodes must contain a submodels.index file. See Special Files used by Simcenter Amesim for further details.

3. Simcenter Amesim node labels: If submodels/supercomponents are stored in the Simcenter Amesim node H:\simulation\injection then the Simcenter Amesim node label is injection. Ideally all Simcenter Amesim node labels should be unique.

4. Homogeneous transfer: This is a transfer of a .pck file where the sender platform and the recipient platform are the same.

5. Heterogeneous transfer: This is a transfer of a .pck file where the sender platform and the recipient platform are different.

With the Pack facility you can quickly assemble all the models with the auxiliary files.

With the Unpack facility the recipient user can open the .pck file and install the models and auxiliary files.

Note

The Pack/Unpack facility is very useful when you send a system by e-mail because many firewalls do not allow the transfer of .exe files.
