Accelerating Sharing in Ansys Discovery

Hello everyone, in this video I want to talk about sharing topology. This is something we need when we have multiple bodies that have common faces together, like for example this cosine. When we have a 2D series of bodies, please be sure to correct any misspelled Ansys product names.

The speed of the shared topology here is that you come to the setting and work with rendering quality that you can see. So usually it is set at 5, that it is mostly for showing the roundness of the faces, circular faces, and curvature, just display curvature of the edges.

If I go for lower quality, you can see that instead of fully rounded edges or faces, we have some little bit of edges on that, it's like a piecewise curve that I put together to make the curve.

And the lowest one is 1. In this video, I want to show you that where we are working with rendering quality, this is one way that we can reduce the time for sharing topology. So, let's start with rendering quality of 1, and go back to the large model that we have here.

And be sure that here, as you can see, the same very low rendering quality is set at 1, and go for sharing topology. So you can see that many of these bodies are here. Let's go and start sharing topology. I will measure the time for that and I will report the time for different sharing topology.

I mean, for different rendering quality when shared topology. Record the time for different rendering quality. So, let's go for sharing topology and start. So it is doing the shared topology. As I said, this model has many faces and edges that need to be shared among these bodies.

So, as you can see, it shared about 2 faces and above 3 edges, and the time for that is about 42 minutes and seconds. So let's go for unsharing. You can see where we shared. Ok, we already shared, now we unshare that, and change the rendering quality to 5, which is the default value.

See that we have much better curvature for the edges and roundness for the circular faces, and do the share topology again. So this is set to 5. Let's start. Thank you for watching!

So it is longer, about 46 seconds, so the previous one was like 42 seconds, and you can see the shared topology, okay, some of them are not shared still. So let's again unshare it and redo it again.

Go to the highest rendering quality, which is 7. So this is the best graphics display that we can have for the curved parts, say for example. Let's start sharing.

This is sharing topology with the highest rendering quality set at 7. I got close results, almost 46, 47. So if we compare the time when we change the sharing topology, when we change the rendering quality for graphics display, it could save time for this specific model up to 10%, which is very good, and for the other models, when we have more and more bodies with thousands of edges and faces that need to be shared for the meshing, then we can see that even 10, 20, something that really can save a lot of time.

Here I have another model, as you can see, that it is like building blocks that attach together. It is a massive model that I can tell you that we have 7400 bodies, so for this one, sharing topology is also important, if we can speed it up or not.

And I so we have here thousands of faces to be shared between the bodies, and also tens of thousands of edges to be shared when we do the shared topology.

Let's see if rendering quality is important here, so it is just one, the lowest rendering quality, let's go and check that, be sure that nothing is shared before, so I can see that how many thousands of faces and tens of thousands of edges, and then we can do the share topology, because it is a very big model with thousands of bodies and faces to be shared, and tens of thousands of edges, as you can see here, okay, so it takes time.

Okay, so let's start sharing topology. I expected it to take minutes to finish sharing topology, so it may take a while, then maybe I can stop the video here and then back to you when it's almost done. Now it is done.

And when we check that, you can see that above 8,000, almost 8,300 faces, and about 73,000 edges. So 8,000 faces, 70,000 edges, almost. So it is an example that when we have a very large model, maybe the rendering quality can help.

So the time is like a bit above two and a half minutes, not much long time. Let's go and check for now the highest rendering quality. So I again unshare. So we undo the sharing topology. Now I don't need to save the file, just recheck and rebook to see how it has been working.

And of course, I'll add some stuff next time. For today's video, I'm going to try to compare the existing model with the one without any packages or project application.

So, as you can see, everything is unshared, and now go and change the rendering quality to the highest value, 7. It will take a while to finish the display setup, and let's start the sharing again. Again, it will take some minutes to finish sharing topology.

I will stop the video and then I'll be back while it is finishing. Thank you for watching, please subscribe, like, share, and comment.

So we almost got very similar time for sharing the topology, although it is a very, very large model, and one reason is that if you check, we don't have any curvature or any specific things that graphics for the display are really affected by the time for showing the topology.

If we change it to the lowest value, which is 1, we really don't notice any changes here to the graphic display, and so the effect of lowering rendering quality here is minimal for such kind of model.

So this is something to think about, but we already showed that rendering quality could be effective in reducing the time for sharing topology when we have many curved boundaries that are common with the bodies that are in contact. And then we can use that way to accelerate the sharing topology.
