Purpose

Converts raw ascii data created by thermomechanical simulator. It reads the specimen length and diameter information from the comment field in the file, then reads the data, which is in a normalized format (in one single line). Finally, converts to data which can be used for further analysis.

Description

The program takes the user input for the raw data file name, then asks the user for the information on type of data file:

  1. TD data file - dilatation, temperature and time.
  2. SS data file - load, strain, and time
  3. ALL data file - temperature, dilatation, load, strain and time).

Parameters

Input parameters

The number of data points to be read is set by the parameter NPOINT, which is currently set to a value of 4200.

The user is also prompted for input and output filenames.

Output parameters

Writes the data to an ASCII file named by the user.

Error Indicators

None.

Accuracy

Program accuracy is given by the measured data, it does not introduce any errors. However, please check the scaling factor (DNUMER = 0.4D+00) and conversion factor (DMAG = 4095.0D+00) in the subroutine CONVER. Also, please check the thermal expansion coefficient values as a check parameter.
