So, if we see the context here, so, if it is assembly, this ANSYS measure the connections going to be created automatically. If we need we can delete it and we can create manually also. So, here you can see there are different type of connections available. So, you can see bond bonded. So, the bonded connection is basically two components will be connected and they cannot be separated and but they can slide. So, here also same thing and this is frictionless, so, that can be easily moved here it is Ralph means that will be of friction.

So, these connections are very important in structural analysis and the computational fluid dynamics. So, even you can see if you click on any contact, you can see here what are the bodies involved in the particular contact and you can visualize that also. So, you can visualize that also. But normally automatic mesh automatic connections will save our time and it works well. If you want we can take those connections also. So, if you want to check we can just click on it then we can see the contacts and this is fish.

So what are the fish you want to connect you can choose it. So now I'm just letting it to be automatic. So, once you have checked with connections and once you are sure with your connections, so then what we can do is we can generate the mesh right. So just generate the mesh. So it will take time because we have a lot of surfaces and we have a lot of internal components. So, you can see here, so it is under process.

So it will take some time and you can see here totally 60 parts are there in that country three has been messed badly. So, and here also you can observe the progress of the mesh. So normally if we have any complicated assemblies, so we can just go with the unstructured mesh, unstructured mesh and we can concentrate only on the areas where the stress concentrations will be more right. So you can see the mesh has been created and there is no errors, right. So you can see based on the shape automatic mesh has been created. So, if we want to modify it still we can modify it, but it looks good for me because all cylindrical parts mesh with tetrahedral mesh and proper connections also we have and click on the connections here even misconnection also we can do, but this is not important here, because already we have checked with the contacts.

So, what we can do is we have to make sure that the quality of the elements so, so, element quality So, hundred percent quality cannot be a cure, but we can see it should be optimal Quality. So, CAD 2.14 hex contains 0.38 still see I didn't use any mess parameters, I'm just leaving it to the default mesh. Because if you see my quality minimum quality is point one four that is pretty good what I feel and maximum also below 0.1. So and even aspect ratio and Jacobian factor. So, those parameters we can still reduce it. Here you can see the relevance sizing course and everything.

So here convictive because here we have a lot of code. So, it has been chosen automatically. So, if we can Modifying these parameters still we can actually do more quality also. So now I'll just leave it like this.
