Ошибка "модуль" объекта Mayavi не имеет атрибута "SplashScreen"
Я использую Fipy ( https://www.ctcms.nist.gov/fipy/) для моделирования 3D-диффузии.
У меня ошибка при рендеринге среды с использованием Mayavi. Мой код:
from fipy import Viewer, TransientTerm, DiffusionTerm, CellVariable, Grid3D, Variable, MayaviClient, numerix
nx=20
ny=nx
nz= nx
dx=1.
dy=dx
dz = dx
L=dx*nx
mesh=Grid3D(dx=dx,dy=dy,nx=nx,ny=ny, dz=dz, nz=nz)
phi=CellVariable(name="solutionvariable",
mesh=mesh,
value=0.)
D=1.
eq=TransientTerm()==DiffusionTerm(coeff=D)
# Mayavi viewer
x, y, z = mesh.cellCenters
xyzVar = CellVariable(mesh=mesh, name=r"x y z", value=x * y * z)
k = Variable(name="k", value=0.)
viewer = MayaviClient(vars=numerix.sin(k * xyzVar),limits={'ymin': 0.1, 'ymax': 0.9},datamin=-0.9, datamax=2.0,title="MayaviClient test")
# End of Mayavi viewer
steps = 100
for step in range(steps):
k.setValue(step)
#eq.solve(var=phi,dt=1)
viewer.plot()
