Potential Condition in Electrostatics

[Wil]

Hello,

I just stumbled over the input field "Potential Condition" in the boundary conditions for Electrostatics.
Since I could not find any hints (in the forum and in the pdfs for solver and tutorials) what this is for, can you please point me into the right direction?

BR,
Wil

Hi

To give Dirichlet condition you would simply give a value, say

Code: Select all

Temperature = 1.23

However, sometimes you don't want to give the condition over the whole boundary. Fox example, when setting Temperature in a CFD case you should only set it for inflow, not for outflow. Then you can use the condition and the Dirichlet condition only applies to the positive values of the condition. For example,

Code: Select all

Temperature Condition = Equals "Velocity 1"

would apply the BC only when x-velocity is positive.

For electrostatics potential it is more difficult to come up with an example but the logic is the same.
