Spline parameter for moving atrium simulation

[lshahid]

Hello,

I am trying to run the moving atrium simulation, but I am getting this error:

Creating initial folders
Loading displacement points
Creating splines for displacement
/home/lshahid/miniconda3/envs/oasismove/lib/python3.11/site-packages/scipy/interpolate/_fitpack_py.py:295: RuntimeWarning: The maximal number of iterations (20) allowed for finding smoothing
spline with fp=s has been reached. Probable cause: s too small.
(abs(fp-s)/s>0.001)
res = _impl.splrep(x, y, w, xb, xe, k, task, s, t, full_output, per, quiet)

The MovingAtrium.py file states that the spline parameter needs to be set objectively.

def eval(self, _, x):
    self.counter += 1
    _, index = self.tree.query(x)
    # FIXME: Set spline parameter objectively
    s = 1E-2
    x_ = splrep(self.time, self.points[index, 0, :], s=s, per=True)
    y_ = splrep(self.time, self.points[index, 1, :], s=s, per=True)
    z_ = splrep(self.time, self.points[index, 2, :], s=s, per=True)

    self.motion_mapping[self.counter] = [x_, y_, z_]

How can I fix this problem? Is there a value of s that works for this problem? I tried iterating with a large range of values of s but none of them wroked.

I would appreciate your help with this.

Thanks,
Labib
