Automating postprocessing for researchers and engineers with Python scripts

Welcome to this comprehensive course on automating post-processing in ParaView with Python scripting! This course is designed for students, researchers, and engineers who work with complex datasets and want to streamline their workflows, automate repetitive tasks, and create visually impactful scientific visualizations.

Whether you’re in aerospace CFD or another field, this course will help you unlock ParaView’s powerful capabilities and take your post-processing skills to the next level. Here's what you'll learn:

Section 1: Introduction

We’ll begin with an overview of ParaView’s interface and scripting capabilities. You’ll learn how to apply basic filters, execute scripts, and dive into remote and parallel visualization. By the end of this section, you’ll know how to set up local or remote servers and harness the power of multiple CPUs to efficiently process large datasets.

Section 2: Working with Steady-State Data

In this section, we’ll focus on handling steady-state data. You’ll discover how to load datasets, manipulate the scene, and create clear and effective visualizations. We’ll also cover how to set up custom layouts using multiple tabs and windows, enabling you to organize your work environment and tailor it to your project needs.

Section 3: Common Filters

Filters are at the heart of ParaView, and in this section, we’ll cover the most commonly used ones. You’ll explore colormaps for visualizing data distributions, learn thresholding techniques for filtering datasets, and use clipping to isolate specific regions of interest. These tools are essential for creating impactful visualizations.

Section 4: Data Analysis and Manipulation Filters

Next, we’ll dive into advanced data analysis. You’ll learn how to use the Calculator filter to create new data fields, integrate variables over surfaces, and compute gradients, divergence, vorticity, and Q-criterion. These techniques will empower you to extract deeper insights from your data and perform detailed analyses with confidence.

Section 5: Data Extraction

Extracting data is an essential step in any analysis. In this section, you’ll learn how to sample data using probes, generate line plots, and utilize the Plot On Sorted Lines filter to analyze connected curves. We’ll also delve into the Stream Tracer filter for visualizing vector fields with streamlines and demonstrate how to display surface vector fields, such as skin friction. These techniques will enable you to focus on and effectively visualize the data that matters most to your goals.

Section 6: Unsteady Data

We’ll tackle time-dependent or unsteady datasets in this section. You’ll learn how to import and manage these datasets, record animations, and apply temporal filters. Additionally, you’ll master particle tracing techniques, such as streaklines, and how to extract data across iterations for thorough time-based analyses.

Section 7: Advanced Animations

Finally, we’ll explore how to create advanced animations that make your visualizations more dynamic and engaging. You’ll learn techniques like orbiting the camera around objects, applying smooth transitions between filters, and combining these methods to produce complex animations. We’ll also discuss how to add realistic renderings for a professional finish to your projects.

Why Take This Course?

This course is packed with practical, hands-on examples that will make you more efficient and effective at post-processing large datasets. While many examples are drawn from aerospace CFD, the skills and concepts are versatile and can be applied across engineering, scientific research, climate modeling, and more.

Your input matters! If you work in a non-aerospace field, I’d love to hear your suggestions for additional topics that could address your unique challenges. Your feedback could shape future on-demand videos tailored specifically to your needs.
