In the previous lectures, we have learned different methods to create mesh. So, why we have to know all those methods. So, the methods are based on the physics means, the type of problem we are solving and geometry shapes available and the resources you can see here. So, here you can see it is not a regular geometry. So, it we are using our different cells here if you see this is a structured quad elements, if you see here, this is the triangle elements are parameter elements with code and name to the slot if you see, we have our pyramid elements with refinement confinement. So, this is how we help to use different elements in different places.

So, if we want to create all those things we should know all those methods what we learned in the previous lecture. So and when we are dealing with the mesh we have come across batch conforming and that independent So, let's see what those things okay this is fine find surface messes fine okay So, there will be two parameters that is batch conforming and batch independent. So, if you use methods, particularly here we didn't use any methods. So, if you use methods, so you can access the element. So, where you help you will get two options, one is batch independent and another one is path conforming. So, these are the few differences between these these two methods, batch conforming and batch independent So, this command is only available when when we use Methods only if you didn't use any method to be comfortable to use it.

So, you can see the patch confirming is bottom means the message is going to create from edges to volume. If it is a patch independent that is completely opposite and so, you're all phases and the boundaries will be matched here faces and edges and vertices. This is not going to be confirmed. So here it is. global and local controls we can use to control the mesh here only. Only for the D featuring quality elements we can use patch independent.

Here. This is compatible with inflation means we can use with the inflation of Even this is also we can use for the inflation. So, and you can you can just see the methods to access here. So, that we can easily identify in the in the money measure if you use the methods. So, the next one here you can see the size controls also if you use batch conforming sizing This is So, you can see how small areas has been concentrated. Same if you see here the differences, patch confirming details how the details have been captured.

So, here if you see, there is a difference you can see here to block is up here. Some more mile block means here number of failures menzer more when compared to here. So, this is regarding the smoothness. So, if you take a section view you can see how it has been taken. So, the next is the service method. So, this is also one of the method available in the mesh methods.

So, you can just select one face and you can just select the other face after selecting the direction then that is going to be speed the face elements to overall body. So, the next thing is multi turn mesh. So, if you have multiple drones like this So instead of using automatic, you can use the multi zone method to where we can create elements in all the regions. So that's how we can use multi zone method and inflation and all those parameters. It is up to us whether if we want to create a structured mesh, we can use it. If we want to go with unstructured mesh, we no need to use any doors, mesh controls.

So these are the advanced mesh controls available. Still, there are a few advanced things about element quality, and a few more things. So in the coming lectures, we'll see all those advanced things and we See the assembly mesh machine also
