b3p 0.0.4rc8

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 .

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
