I'd like to create a sub-class of Expression,
class my_expression(Expression):
def __init__(self, V, x):
self.x =x
Expression.__init__(V = V)
but I'm having trouble with the constructor - I get the below error. Any
tips?
Garth
line 120, in __init__
raise TypeError, "Expression need to be initialized using either a
'cpp.FunctionSpace', using kwarg 'V', or an 'ufl.FiniteElement' using
kwarg 'element'."
