Periodic Tessellation error

[rsooraj]

Describe the bug

Trying to produce periodic tessellation, with periodicity along X-direction, Neper shows the following error after running for some number of iterations.

The commands used and the error displayed are as follows.

$ neper -T -n from_morpho -oricrysym cubic -periodicity x -domain "cube(2,5,5)" -morpho voronoi,"diameq:lognormal(mean=0.11,sigma=0.042),1-sphericity:lognormal(0.145,0.03)" -morphooptistop itermax=1000000 -statcell diameq,body,npolynb,sphericity,convexity,nseednb -o c_2x5x5_per_lognorm_mu_11e-2_sig_42e-3_10L_iters_VOR -oridescriptor euler-bunge -format ply,tess
