tecreader

python reader for binary Tecplot data using pytecplot

Introduction

This reader wraps Tecplot's pytecplot API functionality in order to handle time series of PLT files. I wrote it for the purpose of reading long series of unsteady flow solutions and assemling them to numpy matrices for further processing.

The module includes provisions for parallel reading via multiprocessing, and is geared very much for files produces by the TAU flow solver - i.e. if you have a different file naming scheme you'd need to adapt some things.

Usage

The simplest use case is as follows:

u, v, w, dataset = get_series(plt_path, zone_no)

• plt_path is the input path containing the raw data time series in Tecplot binary format

• zone_no is an integer or a list of integers denoting the zones to be loaded

• u,v,w are the velocity components represented as matrix of shape (points, samples)

• dataset is a Tecplot dataset object

There are various utility functions, such as for saving results (save_plt) or obtaining coordinates (get_coordinates)

Requirements

• numpy (tested with 1.12.0)
• pandas (tested with 0.19.1)
• pytecplot (tested with 0.11.0)
