WUFI Graph not working in 1D but 2D

[yihao92]

I manage to run a simulation with 1d.
But the result doesnt appeared in wufi graph.
It only show blank and only 2d result file can be shown

For anyone with the same issue: This happened when an older version of WUFIGraph was installed by the WUFI 2D 3 installers after installing WUFI 6. A workaround is to simply reinstall WUFI 6 again.
