Hi,
We are seeing an issue with a simple 1D convection code that worked correctly about a year ago. Here's the relevant snippet. When we call Apply, we now get an exception
netgen.libngpy._meshing.NgException: In ComputeNormalsAndMeasure SIMD: not implemented yet!
I think this is occurring in fem/intrule.cpp in line 3423 of the method ComputeNormalsAndMeasure in the context of a SIMD_MappedIntgrationRule.
Code:
p = 4
mesh = ng.Mesh(make1dmesh(100))
fes = L2(mesh, order=p)
u, v = fes.TnT()
beta = 1
n = ng.specialcf.normal(mesh.dim)
Fu = beta * n * IfPos(beta * n, u.Other(), u)
c = ng.BilinearForm(fes)
c += SymbolicBFI(-u * beta * grad(v))
c += SymbolicBFI(Fu * v, element_boundary=True)
u = ng.GridFunction(fes, 'u')
u.Set(10.0 * exp(-10.0 * ng.x * ng.x))
t = 0
dt = 0.0001
tend = 10
r = u.vec.CreateVector()
while t < tend:
c.Apply(u.vec, r) # The error occurs here
...
Thanks for any help on this!
Best,
Dow
