geometry_gmsh module

geometry_gmsh.blade_CAD_geometry(shapes, outfilename, msh=False)

Write blade into CAD file .stp using gmsh, if msh=True create unstructured surface mesh

Parameters:

• shapes – coordinates of airfoil shapes defining blade

• outfilename – name of output file

• msh – (bool) create unstrunctured surface mesh and save .msh file as well, defaults to False

geometry_gmsh.write_geofile(shapes, outfilename, n_spanwise=300, n_te=3, n_cross_half=100)

Create structured surface mesh using GMSH and .geo file

Parameters:

• shapes – coordinates of airfoil shapes defining blade

• outfilename – name of output file

• n_spanwise – number of cells in spanwise direction, defaults to 300

• n_te – number of cross points in trail edge, defaults to 3

• n_cross_half – number of upper and lower cross section points, defaults to 100
