Disk output from MELTS comes in two varieties. A comprehensive output file named melts.out records a continuous record of the evolution of the system at every stage in a model calculation. If MELTS version 1.1.3 or greater is running, then the results written to melts.out are also neatly formatted into one or more tabular output files named melts-liquid.tbl and solid phase name..tbl
Here is an example of a typical entry in the melts.out file. Click on an item of interest to get a description.

The file melts-liquid.tbl is always created when MELTS version 1.1.3 or greater is run. The first record contains the following field labels, delimited by commas:
Subsequent records contain numerical values corresponding to these quantities. melts-liquid.tbl may be read by standard graphics software that can import data tables with comma delimited fields.
The remaining *.tbl files (output by MELTS version 1.1.3 or greater) contain information specific to mineral phases crystallizing from the magma. File names correspond to the mineral name with the .tbl extension. The files are created only if the mineral appears in the system. Records are written only if the mineral is crystallizing. When more than one composition of the same phase is crystallizing simultaneously (i.e. two feldspars or three pyroxenes), multiple r ecords are written containing the coexisting phase information.
The first record contains the following field labels, delimited by commas:
Subsequent records contain numerical values corresponding to these quantities. The *.tbl files may be read by standard graphics software that can import data tables with comma delimited fields.
