You cannot create EoS within the Eosfit7-Pinc program, and you cannot fit data to create an EoS. Therefore, before using EosFit7-Pinc you must have .eos files for your host and inclusion phases.
- You can create these files with other programs in the EosFit7 program suite
- You can download them from www.rossangel.net
- A few files are provided in the \examples folder with the installed executable, and more are available at www.rossangel.net.
- You can import EoS from the Thermocalc software, dataset ds62.
Load the .eos files for the host and the inclusion by using the buttons in the EoS tab:
- The select file button launches a file browser where you can choose and open an .eos file.
- When an eos is loaded, the parameters are reported in the information panel.
- If you are running the program in expert mode, you will see more information in this panel than is shown here.
- The Import Thermocalc button allows you to import EoS parameters from the Thermocalc database, if you have the data base file.
- This only reads versions of the Thermocalc database from ds62 and later. If you have earlier versions, use the EosFit calculator or EosFit-7c to input the parameters by hand, save them in an .eos file, and then read that file into the EosFit7-Pinc program.
- Important: the model for Landau-like phase transitions in Thermocalc is subtly different from that used in EosFit7. Therefore, if you import an EoS with a Landau phase transition (e.g. quartz), then EosFit7 will calculate volumes at P and T that may differ by about 0.05% from those obtained in Thermocalc.
- The import dialogue also allows you to set the shear modulus (G0) for the host crystal at room P and T
- When you have loaded an EoS for the host and the inclusion, the tabs for calculation will become active, as shown below:
