Dear Bilgin, Try project instead of interpolate, i.e. project(my_initial_condition_expression, Hermite_space) Hope this helps, Patrick On 28/02/2021 11:44, bilgin@metu.edu.tr wrote:

Hi there,

I just want to ask If I use Hermite Element, how can I use expression as initial condition. Since I can not interpolate expression to function space that is constituted by hermite element.

Are there any examples(code snippet) you can share with me?

Thanks in advance, Bilgin
