Hey guys, Thanks so much for the previous help. I've googled this question to no avail. Presently, I have 4 nodes in order (node 1, node2, node3, node4) with axial Spring2 elements connecting node1 to node2, a rigid body connection connecting node2 to node3 and another axial spring2...

To clarify, I found out axial stiffness was incorrect along with some parameters in my beam definition. BTW, when defining nonlinear beam, it seems shear is calculated automatically for the section as opposed to user inputs for bending and axial stiffness. Is this true and if so, how is shear...

Hey guys, Thanks alot for the help. I was able to resolve the problem via using nonlinear beam section geometry!..=).

Thanks alot for replying. Do I define contact properties via *Contact Controls? I want one body to slide frictionlessly against the other once contact has occured with no penetration but I'm unsure how to go about this? My approach so far has been to set absolute penetration to zero with a delay...

Hi all, I'm trying to model bearing effects of 2 bodies composed of elastic materials defined as *Surface. I am placing a displacement control on to one of the bodies and am connecting the two using beam elements. Contact pairs is used with small sliding, surface to surface. When I run the...

Hey guys, I have 2 questions, one is easy and one is hard. I have a bitmap image file thats in black and white. How can I invert the black colors into white colors and white colors into black colors? My second questions is, I would like to scan the image with a nxn square where n is a...

Yea Mike, im reading a MATLAB intro book for engineers. Unfortunately Im just beginning to program this week. BTW, your way definitely worked. So what you are saying is a for loop only gives one answer after many repetitions of mathematical calculation? Thanks

*replace x with array*

Guys I tried for i = 1:1:length(array)-1 answer = x(i)+x(i+1) end Would this be a correct approach?

Hey guys, This is the opposite of my last question. How do you find sums of consecutive array entries? I need them to be displayed however and therefore cannot use the sume function. By this I mean [4 5 6 7] = [9 11 13] Ultimately I want to use diff(x).*(sums of y).

Wow...I feel stupid. Thanks for the tremendous help you guys!. BTW, is there a good website to reference for programming help?

Hi, Im a beginner at matlab so please bear with me. I want to create a function that has 2 inputs from a datafile. Both are individual columns of a three column data file with input 1 as column 1 and input 2 as column 2. Is there a way I can make a formula to find the differences between...
