Software with stiffness matrix

[jnzach]

I was wondering if anyone knows of a website or just some information on any kind of software that you can draw a structure and then run the program and it will give you the stiffness matrix for that structure. Thanks

Exactly what are you trying to accomplish?
If you want the stiffness from point A to point B in matrix form, then you can do that with any program.
Please clarify your question. What is your intent?

I want to analyze a frame problem, (im a senior in college) and was wondering if there is a program where I can draw the problem out and then run the program and it will show me the stiffness matrix for that problem.

ANSYS can do all your request but it quite difficult for who not familiar with FEM program.
If your frame have not many element you can form stiffness matrix by inverse the flexibility matrix by mean of force method , this method you can use any software.Is it what you want?

You can very well do this with high end solvers like ABAQUS. I know that you can store the stiffness matrix from ABAQUS. Other softwares, hmm even IDEAS may have an option to list the K matrix onto the lis file.

Good Luck.

jnzach,
Try looking at IntuativeFEM - a very nice program to use. It has a nice interface but only basic functionality. However one nice feature is that you can examine the stiffness matricies and it writes them in a user frendly form. Look at the following link:
