Hi,

I am running Silvaco Mixedmode with a cylindrical atlas device. In my SPICE-like circuit description, I have already used the cylindrical options:

.options CYLINDR

However, when I run the simulation, the following error occurred:

Error: Electrode # 1, SOURCE , has zero thickness.
A DEVICE3D electrode must have an associated thickness.

The SOURCE electrode is defined in Atlas as:

ELECTRODE NUMBER=1 NAME=SOURCE R.MIN=7 R.MAX=8 A.MIN=40 A.MAX=50 Z.MIN=-0.11 Z.MAX=0

What could be the problem? Thank you.
