Device error: Attempting to insert vertex outside of convex hull

i don’t know if i put the topic in the right catagory, if i did not, please put it in the correct catagory.
i have this error “attempting to insert vertex outside of convex hull” when i am running simulation in device. I don’t know what is causing this error. i saw a question regarding this error in knowledge base, but as it was not in english, i could not understand the answer. any help will be really appreciated. thank you.

Hi @mrinmoy, The error message tells us that the solver faced a problem during the geometry building. If you are running an older version of DEVICE then please upgrade to the latest version (you can download it from here: If the error persists then try following the second suggestion in this post: Geometry building issue in 3D simulation for DEVICE.
