a runtime error

[kheirdast]

Hi Eric,

I've tried to run one of the jupyter notebooks: "diff1d_0_BFG", by running the following error is raised after the following box:

eq_name = 'diff1d_0'
eq = PDE2DIFF1D(eq_name)

--------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)
<ipython-input-36-47a85d6bb182> in <module>
      1 eq_name = 'diff1d_0'
----> 2 eq = PDE2DIFF1D(eq_name)

~/Documents/PDE/nnode/pde2diff1d.py in __init__(self, diffeqmod)
     46             assert pdemod.dG_dYf      # dG/dY   Y=Y(x,y,t)
     47             assert pdemod.dG_ddelYf   # dG/dgrad(Y)
---> 48             assert pdemod.dG_ddel2Yf  # dG/d(grad(Y)grad(Y))
     49             assert pdemod.bcf         # Array of initial condition functions
     50             assert pdemod.delbcf        # Array of initial condition gradient functions

AttributeError: module 'diff1d_0' has no attribute 'dG_ddel2Yf'

How can I possibly solve this issue?

Kind regards,
Navid
