Hi,
I have difficulties with plotting a constant function in dolfin version
0.9.4. I can do it in version 0.9.3, but need it to work in 0.9.4 too.
The problem is that I have different values in the x and y directions, 0
and 9.82 respectively.
The code is as follows:
------------
mesh = Mesh("circle.xml.gz")
# Define function space
V = VectorFunctionSpace(mesh, "CG", 1)
W = FunctionSpace(mesh, "CG", 1)
# I have tried with two different definitions of the function, but don't
know which one is correct:
# Expression for acceleration force
class Acceleration(Expression):
def eval(self, value, x):
value[0] = 0.0
value[1] = -9.82 # 1g acceleration downwards
f = Acceleration(V=W)
g = Constant(mesh,(0, 9.82)) # I can plot g in dolfin version 0.9.3 and
it works correctly there
-----------------------------------------
Do the Constant definition of g also work in dolfin version 0.9.4 even
if I can't plot it?
