Eos Utilities


EosFit Calculator

This is a GUI built on the Eos cfml library to act as a rapid P-V and P-V-T calculator. You can use it to calculate P from V and T, V from T and P, etc.

The calculator saves and reads in EoS parameters with the 'eos' files, so you can use EoS you have determined in EosFit-7c and EosFit-GUI.

Latest Update: June 2021
New features in this version:
  • Includes all updates to EoS models applied to EoSFit-7c and EosFit-GUI.
  • Display of heat capacity calculated from EoS parameters.


The EosFit calculator is automatically installed when you install the EosFit program suite in any system: MAC, Linux or Windows.

EosFit-Pinc

This is a GUI built on the Eos cfml library to do rapid calculations for elastically isotropic spherical host-inclusion systems. It duplicates some of the functions in the isomeke utility of the EosFit7c program. EosFit-Pinc can:
  • Read EoS as .eos files from any other EosFit7 program.
  • Import EoS from Thermocalc.
  • Calculate final inclusion pressures from known entrapment P and T.
  • Calculate entrapment isomekes from measured remnant inclusion pressures.
  • Calculate isomekes and isochors of the two phases.

EosFit-Pinc is only available for Windows. The methods and program are described in: Angel RJ, Mazzucchelli ML, Alvaro M, Nestola F (2017) EosFit-Pinc: A simple GUI for host-inclusion elastic thermobarometry. American Mineralogist, 102, 1957-1960.


Latest update: June 2021.
New features in this version:
  • Includes all updates to EoS models applied to EoSFit-7c and EosFit-GUI.
  • New output window with more information and results.
  • Improved algorithms to calculate isomekes to handle previous problems with sharply-curved isomekes (e.g. with quartz near its alpha-beta phase transition).
For full details of changes, please consult the help system.

Installation:
  • If you have an earlier version, uninstall it by using the Uninstall utility in Windows.
  • Download the EosFit-Pinc installer and run it.
  • It will install the EosFit-Pinc program, some example .eos files and the EoSFit-7 help system.
  • All files will be in C:\Program Files (x86)\EosFit7Pinc.
  • Read the help system to understand how the program works and the basis for the calculations.
