While working with CFD-VIEW, the user has the option of saving an mdl file. This file stores all the entities created in CFD-VIEW, from the point the DTF file (or other data file) was imported, to their current state at the time of saving. The user can thus reopen this file anytime later to resume work.

By default, the ‘Save All Data with Model’ option under the File menu is checked (see figure 1), making the mdl file store all parts of the model, including the data that was read from the DTF file. Although this makes the file independently portable, the file size can be large.

 If the user does not plan to move the DTF file from its current location, the above option can be unchecked before saving the mdl file. The mdl file will then store only a link to the DTF file instead of the entire DTF data, thus significantly reducing its size.

If you have any questions about this feature or would like us to discuss some other topic in the future, please let us know.
