Chaffra is still having a problem:
Thanks for the answer Johan, but don't you find it awkward that
f = Function(V)
f.evaluate( x, {}, (), {}) returns the same object instead of f(x).
I run into that problem for my application. To remedy I added the code
below to ufl.terminal.evaluate. Of course this does not work yet when
derivatives are present but at least i do not have to project all the
time when I just want an evaluation.
I don' t know what the implications are for ufl and dolfin but maybe
this could be added to the ufl code.
---added to ufl.terminal.evaluate
#try to use self as mapping
try:
if callable(self):
if derivatives:
f = self(x, derivatives)
else:
f = self(x)
return f
except Exception as e:
print traceback.print_exc()
raise e
