"BFGS update error2" error with meshing module

Dear Roman,

I am trying to mesh post the tess module, for CPFEM simulation. I get the following error during the tet mesh:

These are the commands I am uisng:
neper --rcfile none -T -n 'from_morpho' -id 1 -dim 3 -regularization 1 -domain 'cube(0.01, 0.00155,1E-3)' -morpho "diameq:lognormal(0.0003,0.0000001),1-sphericity:lognormal(0.145,0.03)" -morphooptistop val=0.005 -o 0-01
neper --rcfile none -M 0-01.tess -rcl "body!=0?100:200" -elttype tet -format inp

Thanks in advance,
Aditya Vuppala.

You can ignore the BFGS update error2 errors as long as Neper runs (which it does on my computer, on this example). These messages are complains from Gmsh.
