GJK error in interpolation between non matching second ordered 3D meshes

Without the actual meshes, it is hard to give you any guidance.

I use code of @Lingyue_Shen to reproduce the same error, which is self-contained.

It is very similar to my use case, except that he shakes every point in the demo as quoted, whereas I keep the boundary points fixed in application. That does not affect the results.

@Lingyue_Shen

# set seed to np.random
    np.random.seed(0)
    movement.x.array[:] += np.random.rand(movement.x.array.size) * 0.1
    msh.geometry.x[:, :msh.geometry.dim] += movement.x.array.reshape((-1, msh.geometry.dim))

@dokken

What happens if you increase the padding tolerance in interpolation data?

I gradually increased padding from 1e-11 to 1, and the error persists.
