b3p 0.1.9

Command line tools for preprocessing of wind turbine blade models

b3p

Command line tools to create models for composite (wind turbine) blades.

Functionality

• Building 3D models of wind turbine blades
• Creating a quad mesh for the blade
• Assigning scalable slab based laminate plans to the structure
• Assembling a shell mesh with laminate properties
• Writing mesh information to VTK files

Install

From pypi

pip install b3p

From source

git clone https://github.com/wr1/b3p.git
cd b3p 
pip install -e .

How to run

usage: b3p [-h] {build,ccx,2d,ccblade,clean} ...

Blade Design CLI

positional arguments:
  {build,ccx,2d,ccblade,clean}
    build               Build the full blade model
    ccx                 Run Calculix operations
    2d                  2D mesh and ANBA4 operations
    ccblade             Run CCBlade analysis
    clean               Clean working directory

options:
  -h, --help            show this help message and exit

In a cloned repository:

cd examples
# build the blade model, geometry, mesh, drape
b3p build blade_test.yml
# run the ccx fea analysis
b3p ccx blade_test.yml  

Output

Plot of geometric input parameters for the example blade
