Eosfit7c Console program

Previous Next


When you start the program, this is what you should see:






In Windows the program often starts with a narrow screen. You can change the width of the terminal screen by:



Information about the program version is displayed, followed by the EosFit7.6> command prompt.


All commands are entered by typing them in at the  prompt.


All of the commands are grouped by usage. For example all of the features related to data handling and fitting (i.e. read, write, select, fit etc..) have been grouped together into one set of commands labeled "Data Handling and Fitting".  


Sets of commands like "general", "EoS Input and Output" and "Advanced" are always available through all the program including each subroutine (i.e. isomeke and input).



LIST OF THE AVAILABLE COMMANDS:

VDP

Do integrals of VdP for free energy 

PVFILE

Calculate properties at a list of P,T points in a file

PTHERMAL

Data handling

and

Fitting

READ

Read a dataset with default extension *.dat unless a different extension is specified (see below).

LIST

List the selected data

SELECT

If the dataset includes more than one variable (e.g. it contains all cell parameters), this selects which variable will be used.

FFCON

Calculate f and F (strain and normalised pressure) values from a dataset.

FIT

Fit EoS to the selected data

GROUP

Group individual data together so they can be used/omitted as a group.

USE

Set the flags to use individual data points.

OMIT

Omit individual data points from further calculations

CLEAR

Delete the entire dataset from EosFit7c (does not delete the file).

SORT

Sort the selected data

EDIT

Edit the entire dataset.

WRITE

Write out the data to a dataset  with default extension *.dat unless a different extension is specified (see below).




Other Utilities

CELL

Utility to calculate unit cell parameters and volumes from EoS so they are internally consistent


MPHASE

Utility to calculate elastic properties and PVT of mixtures of phases from their EoS


STRAIN

Calculates strain and property tensors from pairs of cell parameters


ISOMEKE

Utility for host-inclusion calculations with the isotropic model.


HOSTINC

Utility for host-inclusion calculations with anisotropic phases.







System & Macro

Commands

TIME

Includes the data and time in the command prompt. This is a toggle: use it a second time to remove the date and time from the prompt.

RECORD

Record commands in to a macro file, so that the sequence of commands can be repeated automatically with the macro command. Terminate recording by typing END

MACRO

Load and run a set of commands from a macro file

END

Only active when RECORD is being used; stops recording of commands to macro file.

SYS

Switch to operating system. After typing SYS, all subsequent commands will be sent directly to the operating system.

PROG

Only active after SYS has been typed. Exits from system, back to EosFit-7c program .

DIR

List files in current  working directory (works just like dir in MS-DOS).

CD

Change working directory (works just like cd in MS-DOS).
