A spirit level is a device used to check the level, flatness, or straightness of surfaces, especially surface plates and machine beds.

It is a basic angular measuring instrument that works using a bubble enclosed in a glass vial.

Due to gravity, the bubble always moves toward the highest point of the vial.

When the base of the spirit level (called the reference plane) is perfectly horizontal, the bubble rests at the center of the graduated scale.

Any movement of the bubble from the center indicates inclination or unevenness of the surface. The amount of bubble movement over the scale gives the angular deviation of the surface.

COMSOL Multiphysics Essentials

You will understand the major COMSOL modules such as AC/DC, CFD, Heat Transfer, Structural Mechanics, MEMS, and Pipe Flow. This helps you see how COMSOL is used in different engineering fields.

You will learn how to customize the COMSOL desktop, use the Model Wizard, access the main menu and toolbar, and follow the basic steps needed to build any simulation model. You will also use ChatGPT to understand sequencing in COMSOL.

You will learn global and local definitions, create variables and expressions, use operators and functions, and load parameters from external text files with AI assistance. This gives you strong control over parametric modeling.

You will work with geometry tools, selection lists, transparency settings, hiding and showing entities, rendering, and user-defined selections. This helps you build clean and accurate models.

You will learn geometry modeling, adding nodes, editing nodes, and understanding the current node. You will also use ChatGPT to assist with geometry features.

You will explore material databases, assign materials properly, work with the material browser, and use external material libraries. You will understand how materials behave in multiphysics simulations.

You will learn how to build full COMSOL models using the Model Builder, manage nodes, enable or disable physics, save files, open model libraries, and explore advanced results sections using GPT-based guidance.

Finally, you will work on multiple learning projects covering named selections, meshing, solver studies, results plotting, friction modeling, and cylindrical roller simulations. These projects help you apply COMSOL to real engineering problems.
