segmentation fault

[bta...@googlemail.com]

Dear all,

I am trying to do a polar molecular calculation with the Gromacs-5.1.x include APBS functinality Linux x86_64. However, when I do the calculation, it keeps showing "segmentation fault". 

I tried to download APBS program but APBS 1.3 and 1.4 doesn't exist anymore. Can someone suggested what can I do to solve this problem? Thank you very much. 

Best,

Ben
