Segmentation fault (core dumped) When visualizing

[bright-men]

I completed the simulation in fepx and when I visualized with neper, I was prompted that "Segmentation fault (core dumped)". What is the reason?
neper version 4.5.0 FEPX version 1.3.1-1

neper -V ../FEPX_example.sim \
>  -step 2 \
>  -datanodecoo coo \
>  -dataeltldrad 0.004 \
>  -dataelt3dedgerad 0.0015 \
>  -datanodecoofact 10 \
>  -dataelt3dcol stress33 \
>  -dataeltscaletitle "Stress 33 (MPa)" \
>  -dataeltscale 0:850 \
>  -showeltld all \
>  -cameraandle 13.5 \
>  -imagesize 800:800 \
>  -print 1_s33_deform

Please give a try to the latest Neper version.

If the problem persists, please provide a minimal working example (what is FEPX_example.sim?).

Sorry, it was my fault. I misspelled the code, which led to this fault. Now I have solved it, and fepx and neper work normally.
