liton_ordered_tec for C++

Ordered_tec is a simple pack writing ordered data (structural data) to a binary tecplot file (.plt). This package does not need any dependency, and it directly write binary files according to Tecplot binary data format.

Features

Basic Features

Support 1, 2 and 3 dimensional data
Support multi-zone file
Support file types including grid, solution and full
Support solution time and strand Id for zone
Support auxiliary data for file and zone

Highlight Features

Auto recognition the data type, supporting five types of data
Support exclude data with Begin, End and Skip
Free setting of echo mode
Complete log system including log in xml and json

Usage

Download and Configuration

You only need to download all folders in scr for using this package.

Before using it in your project, you need to copy these folders into your project directory or somewhere else to make sure that the complier could find it.

Coding

The Tecplot file consists of zones and data are storage in zone. Zones describe different set of data in space or in time. All the numbers of data in different zones in one file are same. Auxiliary data is extra data attached to file or zone which can be seen and used in Tecplot.

There are six classes usually used included in the liton_ot namespace. They are TEC_FILE, TEC_ZONE, TEC_DATA and correspondingly TEC_FILE_LOG, TEC_ZONE_LOG, TEC_DATA_LOG used to contain log.

To use the package, first you need some including and namespace declaration.

# include "ordered_tec.h"
using namespace liton_ot;

Then you need to declare a TEC_FILE object and set its properties. The property Variables is a string vector containing the variables' name which is required.

TEC_FILE tec_file;
tec_file.Variables.push_back("x");
tec_file.Variables.push_back("y");
tec_file.Variables.push_back("z");

You can also set some other properties optionally.

tec_file.FileName = "Test";
tec_file.Title = "Test";
tec_file.add_auxiliary_data("a_data_1","test01");
tec_file.add_auxiliary_data("a_data_2",0.5);

Then attach a TEC_ZONE object to the file and set its properties.

tec_file.Zones.push_back(TEC_ZONE());
//x, y, z are the point to the data, the size of all data is 10 by 30
tec_file.Zones[0].Max[0] = 10;
tec_file.Zones[0].Max[1] = 30;
tec_file.Zones[0].Data.push_back(TEC_DATA(x)); //auto recognition point type
tec_file.Zones[0].Data.push_back(TEC_DATA(y));
tec_file.Zones[0].Data.push_back(TEC_DATA(z));

You can also set some other properties optionally.

tec_file.Zones[0].ZoneName = "zone_1";
tec_file.Zones[0].StrandId = 0;
tec_file.Zones[0].SolutionTime = 0.1;
tec_file.Zones[0].Begin[1] = 1; //begin of data offset 1 in second dimension
tec_file.Zones[0].End[0] = 2; //end of data offset 2 in first dimension
tec_file.Zones[0].Skip[0] = 2; //skip to write data by 2 in first dimension
tec_file.Zones[0].add_auxiliary_data("a_data_1","test01");
tec_file.Zones[0].add_auxiliary_data("a_data_2",0.5);

Before write data, you can set echo mode optionally.

tec_file.set_echo_mode("full","full");

And write data.

tec_file.write_plt();

Now you can get log in tec_file's property last_log. Also you can write the log in a xml file.

tec_file.last_log.write_xml();

Compile

The file functions are based on 32 bit, so it is not supported to write big file over 2G. Try to split data into small files.
