Regularized meshfree method

Okay kiddo, let me explain what regularized meshfree method is in a language you'll understand!

So, do you remember playing with a tub full of water and a toy boat? You could move the boat around and make waves in the water. But, what if you wanted to know how the waves would move if you put two boats in the water? That's where regularized meshfree method comes in!

When scientists and engineers want to study how things move in water or air, they use complex equations to calculate the movement. But, these equations need a "mesh" - a grid of points - to work properly.

Now, a regularized meshfree method is like a pretend mesh that scientists use when they don't want to use an actual grid. Instead of a grid, they imagine tiny balls called particles floating around in the water or air.

These particles are connected by imaginary lines, like strings, that help show how they move together. And, with a regularized meshfree method, scientists can use these particles and lines to calculate how waves and air currents move around objects like boats or planes.

It's like playing with a tub of water and toy boats, but using your imagination to understand how the waves move in a more complex way.

Does that make sense, kiddo?
