Metric advection demo #144

Closed ddundo closed 2 months ago

ddundo commented 3 months ago

I've done the bubble shear test case with metric advection - would it be useful to put it up as a demo? I don't know how niche this is :)

jwallwork23 commented 3 months ago

Sure, go for it!

ddundo commented 3 months ago

@jwallwork23 could you please tell me how you computed the "relative L2 error" in the bubble shear section in your thesis? I'm thinking what would be the best way to interpolate the fields such that they're on the same mesh - i.e. interpolate the final solution or the initial one onto the other one's mesh, or onto a fine resolution uniform mesh?

I'm also curious how you computed the relative error considering there are 0 values of the concentration field. I don't know if there's a more elegant way to do it than just manually handling those :)

Here’s the code. It appears I redefined the initial condition on the final mesh. I think the relative error is meant as a quotient of spatial integrals, rather than pointwise? (I don’t have the thesis open- am on the train.)

Ah sorry, I should have thought myself to look at the code :) thanks for this!

Hi, I am interested in this demo. where can I find the files ?

Hi @karimnorouzi, the PR is under review at the moment (https://github.com/mesh-adaptation/animate/pull/145) so you can look there. It will likely get merged within the next week
