Video Tutorial : How To Implement Finite Element Method 4

In the previous post I discussed the procedure for finding out the global stiffness matrix through local elements. In this post we are going to take this process further, develop the entire linear system, elaborate on finding out the force vector and finally solve the system by applying boundary conditions.

From this post we saw how to formulate one row of the stiffness matrix. But this is not how you want the computer to calculate it. In this post we are going to explore, through some animations, how to calculate the entire global stiffness matrix by assembling local or elementary matrices. Please make sure to read the instructions at the end to view the animations full screen and to have play and pause control.

Latex for Bloggers: Watchmath not Working

Alright a little diversion. For those of you who have seen previous posts know that I use a lot of latex equations. You can too it is simple.

Writing Latex Equations

Here are a few simple steps which you could find on a number of blogs. I am sorry if I do not remember those tens of blogs / sites to give them due credits.

1. Go to the design tab of your blogger dashboard.

2. Then click the Page Elements.

3. By default you should have your blog post on the left and some free space on the right (with some default gadgets already included). This should be the layout of your blog page.

4. On the right hand side of your page, click add a gadget. Another window will pop up. Scroll down in this window until you fine HTML/Java Script. Click on the plus sign and it will be added.

5. In the configure HTML/Java Script window copy and paste the following code:

In the previous post I discussed some fundamental concepts in implementing the finite element method. In today's post we will move further. The post ends with a small animation on the calculation of the stiffness matrix.
