Hi,

The error is: 

This is the entire view:

Thank you. I have tried to expand my simulation area, but the error is still occurring. My groove width is approximately 1.5 um along the x-axis, and its height along the y-axis is about 0.3 um. The FDE range along the x-axis is 2 um, and along the y-axis is 6 um.
