[Archive] Some help for beginner

Message by Siddharth Krishnamoorthy:
I am very new to SPIS and fumbling my way through it. I essentially want to examine the I-V characteristics of a Langmuir double probe in a plasma. I have created a simple computational domain using gmsh such that the two probes stick into the plasma from one of the boundaries. Can someone help me on which boundary conditions to specify on these two probe surfaces? Also, if I wanted to measure the current collected at these two probe boundaries, how would I go about doing that?
Thank you for your help!

The two probes are simple spacecraft surfaces. You can select a Vsweep with the potentialSweep scenario at global param level
