Is complex mode supported?

[JunmingDuan]

Dear all,

I have searched around but found no tutorial related to the complex number.
The complex mode is mentioned in UFL document, but I don't know how to use.
For example, if I use
f = Function(V)
f.interpolate(1j*x),
it reports "ufl.log.UFLException: Unexpected complex value in real expression"
Is it possible to use complex number now?
Thanks for any help!

Hi Junming, You need to install a separate firedrake distribution that uses complex instead of real numbers. This is done by passing —complex to the install script. all the best cjc On 8 Oct 2022, at 17:39, Junming Duan ***@***.***> wrote:  Dear all, I have searched around but found no tutorial related to the complex number.

And you might want to create a separate virtual environment through —venv-name
