Simulating Plasma Sheaths: Langmuir Probe Tutorial | Plasma Simulation Series Part 2

Welcome to Part 2 of our Plasma Simulation series! In this tutorial, we dive into a practical diagnostic application by simulating a Langmuir Probe using the Particle-in-Cell (PIC) solver in Ansys Charge Plus. We walk through the entire workflow, from building the geometry to visualizing the formation of plasma sheaths and depletion regions under different voltage biases. You will learn how to configure low-density plasma environments, assign electromagnetic boundary conditions, and interpret the physics of electron and ion behavior. 🚀 What you will learn in this video: Geometry Setup: Creating probe and plasma volumes using the Prepare tab. Domain Configuration: Setting up the "Plasma Dynamics" simulation type and time-stepping. Plasma Environments: Defining Electrons and Argon ions (Ar+) using the PIC solver. Excitation: Creating a Linear Ramp signal to sweep probe voltage. Results Analysis: Using EMA3D Connect to visualize the expansion of the plasma sheath and compare positive vs. negative bias scenarios. 📺 Catch up on the series: Part 1: Exploring Plasma Simulation (Introduction to Ansys Charge Plus) -    • Ansys Charge Plus Overview | Plasma Simula...   Read the full Blog Post: https://blog.ozeninc.com/resources/si...
