How to start learning fluid mechanics in numerical analyses?

 Fluid mechanics with numerical analysis, also known as Computational Fluid Dynamics (CFD), is a powerful field! Here's a roadmap to get you started:

How to model crack propagation in Ansys ?

 Ansys offers functionalities to model crack propagation through the Ansys Mechanical software and the SMART Crack Growth feature. Here's a general breakdown of the process:

1. Pre-Processing:

• Geometry and Mesh: Define the geometry of your model in Ansys Workbench. Ansys Mechanical's Unstructured Mesh Method (UMM) can automatically generate a mesh suitable for crack simulations, reducing preprocessing time [Ansys white paper on SMART Crack Growth & Fracture Modeling].
• Material Properties: Assign material properties to your model, including the fracture toughness which plays a critical role in crack growth behavior.

How to start with Ansys - the story :)

 Ah, Ansys, the engineering playground where you can virtually torture materials before they ever see the light of day (or a real, non-virtual hammer). Here's how to dive in without getting poked by digital shrapnel:

Hey there, thrill-seekers! Ever wondered what it'd be like to pour molten metal like a blacksmith in a bad reality show? Well, curiosity might have killed the cat, but it doesn't have to vaporize your eyebrows (yet). Before you grab that rusty ladle and head for the scrap yard, let's get schooled on some fiery facts:

Best OpenFoam tutorials for beginners ?

 Here are some of the best OpenFOAM tutorials for beginners to get you started:

Official Resources:

• OpenFOAM Wiki Tutorials: The official OpenFOAM Wiki offers a comprehensive collection of tutorials categorized by skill level and topic. The "First Glimpse" series and "3 Weeks" series are particularly well-suited for beginners (https://wiki.openfoam.com/Tutorials).

Is there a possibility to install OpenFoam on Windows ?

 While OpenFOAM itself isn't officially supported on Windows, there are a couple of ways to run it on your Windows machine:

1. Windows Subsystem for Linux (WSL): This is the recommended approach by the OpenFOAM community. WSL allows you to run a Linux distribution like Ubuntu directly within Windows. You can then install OpenFOAM on the Linux subsystem and access it through the command line. This offers a more native OpenFOAM experience.

2. Docker: Docker provides a containerized environment for running applications. There are pre-built Docker images available for OpenFOAM. This can be a good option if you don't want to deal with installing Linux directly on your system.

For what cases in Ansys CFD software I can use isotropic materials , and where anisotropic ?

 In Ansys CFD software, you'll use isotropic materials when the material properties are the same in all directions, and anisotropic materials when the properties vary depending on direction. Here's a breakdown to guide your material selection:
