Title: error
Post by: chitrapandy on June 14, 2021, 03:33

Hi,

I have calculated Id-Vg for my transistor structure. At the first time I have viewed the IdVg using IV characteristics analyzer but now below error is shown

Traceback (most recent call last):
  File "IdVG_300K.py", line 1573, in <module>

How to rectify this error? Help me to solve this issue.
Thank you

It looks like the HDF5 file has become corrupt. Might be easier to just rerun the calculation...
