Hello, everyone,

I am currently working on a TFT project, specifically using the bottom gate top contact model. While trying to extract the "tox" values of SiO₂, I encountered the following error:

"extract name="tox" thickness material="SiO~2" mat.occno=1 x.val=0

WARNING: x value is out of bounds of structure (min=1.79769e+308, max=-1.79769e+308)

defaulting to left hand side @ x=-1.#INF

WARNING: specified cutline may give inaccurate values resulting from proximity to structure edge, (min=1.79769e+308, max=-1.79769e+308)

ERROR: failed extracting 1d cross section

Extracted results: N/A

Check cut line and/or selected quantities"

Can anyone explain why this error is occurring and how to correctly define x.val?
