The look-up tables may be stored in a file that you can read back into later sessions of FLUENT. FLUENT will use the tables to extract the species, density, and temperature fields from the mixture fraction field that it predicts as part of the flow-field calculation. The look-up tables should be saved before you exit from the current FLUENT session.

By default, the file will be saved as formatted (ASCII, or text). To save a binary (unformatted) file, turn on the Write Binary Files option in the Select File dialog box.
