Hi,

I'm currently trying to model this beam shown below in ANSYS APDL. I'm very new to the software so I'm still trying to get the hang of it and I need to learn it for my undergraduate studies.

But the problem is, whenever I do try to model it on APDL, the structure looks like this:

Is there any way to orient it similar to the intended structure in the first image? Any help would be appreciated.

The code that I generated looks something like this, just for reference. Any help would be greatly appreciated.

/PREP7 ! Enter preprocessing phase
! Define keypoints
K, 1, 0.05, 0, 0
K, 2, 0, 0, 0
K, 3, 0.15, 0.06, 0 ! This keypoint is where the force, P, is
K, 4, 0, 0.12, 0

The way it works is you have just one line between two points, a distance L apart.

The cross section is applied to that one line.

Thank you, I will give it a try. I also wanted to ask, when applying constraints, since at one end of the channel it is a fixed support, do I then just apply it to those two points you've mentioned? Much appreciated

You apply the fixed support to one vertex.
