NLVE: General description

Purpose

Data Files

• The first line of the file should contain the sample parameters separated by semi-colons (;). It may contain any number of parameters which will be read and saved as file-parameter in RepTate. In unit-aware applications, a file parameter value may also include an explicit unit, for example Mw=1131 Da;T=25 ºC;gdot=0.1 1/s;.

• Then the data columns should appear, separated by spaces or tabs.

• In unit-aware applications, column headers may include units in square brackets or parentheses, for example t [min] or G' [kPa]. See Units for the supported units and current limitations.

.shear extension

Text files with .shear extension should be organised as follows:

• .shear files should provide parameter values for

  1. shear rate, \(\dot\gamma\)

  2. temperature, \(T\)

• 2 columns separated by spaces or tabs containing respectively:

  1. time, \(t\),

  2. shear stress growth function, \(\sigma^+(t)\),

A correct .shear file looks like:

gdot=0.1;T=160;
2.50E-01 845
7.50E-01 1830
1.25E+00 2490
...      ...

.uext extension

Text files with .uext extension should be organised as follows:

• .uext files should provide parameter values for

  1. Hencky strain rate, \(\dot\varepsilon\)

  2. temperature, \(T\)

• 2 columns separated by spaces or tabs containing respectively:

  1. time, \(t\),

  2. tensile stress growth function, \(\sigma_E^+(t)\),

A correct .uext file looks like:

gdot=0.1;T=160;
2.50E-01 845
7.50E-01 1830
1.25E+00 2490
...      ...

Warning

The first line of the .uext file provides the flow rate as gdot=0.1, not edot=0.1
