Electric displacement field in ISFET tutorial

Please login with a confirmed email address before reporting spam

Dear Community,

I am trying to go through the ISFET tutorial, when setting up the electrostatics for electrolyte, the tutorial says that I should specify D0 vector in the boundary electric displacement field as semi.nD ins semi.nX and semi.nD ins semi.nY. But when typing these two in, they are in yellow (which means they are unknown) and when computing, an error says they are not defined. So how can I define them?

Thank you very much!

Feng
