And the background is we came up with this rather complex challenge and to solve it we started simply with a 2D plate with a hole and then we moved to something axisymmetric and then at the very end we were able to check it against this real model and we knew it could be right because of the background of doing the 2D plate and the 2D axisymmetric.

So let me show you where we started from.

So this was where the initial challenge was, it's a nonlinear analysis, it's called contact and this is a helicoil and this is a preloaded setup where we're preloading the thread through this section and the stresses and we were a little bit unsure if the stresses were correct and so we wanted to do a vector plot.

So we backed up, it's okay, let's do something that we know and this is where it's a standard hole in a plate, 2D, and we know we should have a stress concentration of 3 in the pattern.

But to do the vectors, we go in, we'll turn on arrow and we'll go down to contour arrows like that and we're going to do 2D components like that and this is where you set up how you want to see it.

We'll do double andered, we'll do it at the center, okay, and arrow will be components and you go to advanced options and this was the key is that the output vectors on arrow one is really going to be two vectors in the y and the x like that and this is the trick.

So, and by the way, we have to turn on transform because they're plates and otherwise the stresses are going to be an individual plate coordinate system so this is in the y like that.

So the transformation is important, you get the transformation right and you pick everything else, you're going to get this and one of the ways we checked it is that we knew this on top had to be 1,000 because that's what we set the stress.

So this is the utility of doing a problem, you know exactly what the result should be so you can say, okay, I got the vector in the right direction, I got it set to 1,000 and then when you go down here, it all makes sense and I hit control G there to redraw and it's at the centroid and that's why it's not showing 3,000 here but the direction is right and as we'd expect, it's compression up here.

So we got that figured out.

Then, since the problem was actually symmetric, that was a little bit harder because it's more of a 3D and you just can't pick the vector direction, you have to align it to the material coordinate system and that's what we're showing here, this is the material coordinate system set in this thing, in this direction, vertical in the Z and that took a little while to figure out that, you know, 3D, you got to do a, you know, coordinate system.

Transform is in the material direction and then you go to contour arrows and like that, same setup.

We're going to do a vector of the axial and the radial and when that's set up, yes.

Now remember, this is actually symmetric so this is a hole, this is a hole in a solid chunk and so the theoretical stress concentration is 2, so 2,000 and but the stresses you see a little bit different angle, I'll hit control G to redraw the arrows and it's just what you'd expect like that and again, compressive and the material direction is shown, I hit F6 to bring up view options and you go down material direction, I can turn that off right there.

So there, then you just have nicer and these are, by the way, these are resultant arrows which means it takes two vectors and so it's always going to be positive.

So even though this is compressive stress here, it's going to show positive, same here and that's because it's resultant.

Now the coup de grace, the more complex and I have this set up to only show, you know, and that is via your contour options here, contour group is only active like that and now what we're doing is we want to show the vectorials like that and it's already set up.

It's set up the same way as the other one, just like this, 2D components and this is where this is really useful to dig into because on a situation like this, stress flows, it's like fluid, it's like a CFD plot and it has to behave like that and we have contact going on and so even though we don't get the positive, you can see how, isn't this beautiful the way this flows and right here, this is compressive even though and you can see what you would normal to this contact interface and then here you see the flow and the circulation and it's just great, it just makes perfect sense and this is one of the great utilities of doing this vector plot is that it really made sense about how the stresses would work and how it would flow.

Well, I'm 30 seconds over, I'm going to stop here and this is how to set up on a contour for doing vectors and also, we want to remind you guys, we have a lot of other tutorials and we have white papers and downloads and videos and all sorts of stuff to help you go through and we're here to support your efforts, so please reach out, call us if you're a client, if you're not a client, we welcome your business.

Have a great day.

Bye-bye.
