Modeler

Ejemplo 1. Placa plana



In [6]:

    
%matplotlib inline
from nusa.mesh import Modeler

m = Modeler()
m.add_rectangle((0,0),(1,1), esize=0.1)
m.generate_mesh()
m.plot_mesh()

Ejemplo 2. Placa con agujero



In [7]:

    
m = Modeler()
a = m.add_rectangle((0,0),(1,1), esize=0.1)
b = m.add_circle((0.5,0.5), 0.125, esize=0.02)
m.substract_surfaces(a,b)
m.generate_mesh()
m.plot_mesh()

Ejemplo 3. Placa con grieta
