Import utility

Parent Previous Next

The Import sub-program in EosFit7c allows you to import EoS from other databases and files. At this time there are two file formats supported:




Import routines for other popular file formats can be added in future. Contact us with the details of the files you need to import and we will explore the possibilities.



The import utility can be started from the main command prompt, or from within the input utility. A list of available file types that can be imported is listed, and you can choose which one to import.


1: Thermocalc import
















This is the EoS imported for Forsterite (abbreviation fo)




The title is set to indicate the source of the data


And the comments explain the conversion of values from the Thermocalc database.



The composition and molar volume from the Thermocalc database are used to set the room-P,T density.


Check the values before finishing the Import by answering Y to the last question.


You can modify any of the values, add further values (e.g. the shear modulus) or modify the comments with the input command.



The imported EoS is not automatically written to an .eos file. If you want to save it to file use the save command.









2: PVT tables import


This utility allows you to import a table of volumes as a function of P and T from a text file. This is useful for materials, such as fluids or gases, which do not have simple EoS of the type supported in EoSFit7. 


After you import a PTV table you can perform all types of EoS calculations in EoSFit7c, but they cannot be used in EosFit7-GUI or the EoSFit7-calculator.


Below is an example of a table file.






When you select 'Table import', you must open the table file from the file browser, and then answer the questions about the table:
