Data files

UVAS uses several types of data files in the commands to add external data to the simulations and also in the DDP file.

In general, these files are organised in two columns, with pairs of data, like in abscissas and ordinates axis.

Concentrations

No interpolation is made in the in-plane lattice parameter. The program only maintains the value until the next one. Data (x,y) must be numbers. Pairs of data must be in different lines.

DDP file (I): One variable dependance. Binding energies

A linear interpolation is made among discrete data. A "-1" is required at the end of the list to indicate DADOS that there are no more data. If a value is not included, DADOS uses the default value. Data (x,y) must be numbers. Pairs of data must be in different lines.

DDP file (II): One variable dependance. Amorphous pockets energies

A linear interpolation is made among discrete data. A "-1" is required at the end of the list to indicate DADOS that there are no more data. Data (x,y) must be numbers. Pairs of data must be in different lines.

DDP file (III): Two variables dependance

Data here are organized in a matrix where the first two columns indicate the index while the third one is used for the parameter value. A "-1" is required at the end of the list to indicate DADOS that there are no more data. Data (x,y) must be numbers. It is not necessary that the data are in columns; DADOS will read them in order. An example is shown:

DA2IN files

No interpolation is made. Data (x,y) must be numbers. Pairs of data must be in different lines.
