- A simple, physics based simulation of freefall - Version 1a
- License: Shareware
- Price:


This is a simple free fall simulation. Time vs. height fallen, and time vs. velocity are plot. Also includes a small verification at the end, for the calculated values of terminal velocity against that obtained from v = u + at. Coming up in Version 1b: inclusion of bounce, version 2a: inclusion of air resistance.

- An extended method to find the value of pi using random numbers inside a sphere
- License: Shareware
- Price:


The MATLAB file contains a method to find the value of pi. This is just an extension of the general method of finding pi from within a circle. It uses 3D-matrices and some more stuffs, which can be very helpful for educational purposes. Also, do change the values in the file, to see for yourself, how the value depends on the number of random numbers generated..... :)

- Finite Difference Laplace Equation Solver using unequal square grid xy grids
- License: Freeware
- Price: 0.00


The attachment contains: 1. Related matlab files. 2. Picture files of possible outputs. 3. A read me text file. 4. A report containing detailed explanations about the basics and about coding algorithm used herein. Finite difference (central) method is applied and solution is obtained for the stream function for Laplace's equation. I have tried to impart a good level of flexibility w.r.t the grid lenghts, position obstruction and its dimensions, dimensions of the channel, etc. I have been successfully achieveing all these but my idea of including non-circular obstructions is still pending and hope to update the upload as soon I shall be done wih it. The code is pretty transparent in its construction and I feel it should not be difficult to alter it to your needs. Use it to your needs, but do pay proper acknowledgment please :). -...

- Monte carlo simulation of two dimensional grain growth - code - version No. 1 (basic)
- License: Shareware
- Price:


Use this code to simulate basic microstructure evolution. This is quite an old code. Will post the updated code in 2D and 3D shortly. This version uses wrap boundary condition and the computation is a bit slower as against the new code. However, I am making some changes to the newer versions. So, watch out for the newer version.. :)

- Rapidly find the points lying inside a cut-off radius
- License: Shareware
- Price:


This completely vectorized code helps you find all points within a cut-off radius from given point. Say, in applications such as Molecular Dynamics, you may be required to find out which atoms lye within a cut-off radius (for example, the Van-der Waals distance of interaction, or say that interaction distance for the Tersoff Brenner Potential, etc..). In any other applications, you may be required to identify a set of points lying within a circle. This code helps you do that job, very fast. This code is completely vectorized and is fast. Please try the code testrun.m to know how to use this code. Thank you.
