Example project, cases and tests for classy_blocks.

Usage

Installation

1. Prerequisites
   1. OpenFOAM (just about any version)
   2. python3
   3. pip install numpy scipy jinja2
2. Fetch classy_blocks in one of the following ways:
   1. As a git submodule: git submodule add [e-mail]:damogranlabs/classy_blocks.git
   2. Just download the code as a .zip file and extract it to your project
3. Run run.py
4. Open case/case.foam with ParaView to inspect the mesh.

Showcase

These are some screenshots of parametric models, built with classy_blocks.

Rectangular ducts (Extrude and Revolve Operations)

3D pipes with twists and turns (Elbow and Cylinder Shapes)

A single channel of an impeller, without volute and with infinitely thin blades:

2D mesh for studying Karman Vortex Street

Helmholtz nozzle, a resonator with sharp edges. See this sketch.

A full volute and suction pipe (impeller mesh is created separately). This has a sharp cutwater that causes a little unphysical overlap but numerically it is just fine and also quite accurate.

A real-life square volute with a blunt cutwater:

Edges and faces, projected to an STL surface

Mesh for studying flow around a sphere, with projected edges and faces

A parametric, Low-Re mesh of a real-life impeller (not included in examples):
