Hello.
In this video we discuss about the property groups now what is the use of property groups.
Suppose you are working in a project that you have your own set of parameters.
For example your thermal conductivity varies some kind of an exponential curve or something like that
but that material is not present in use a library.
So how will you do that.
In those cases you have to use user defined property group what it means is the user will define the
property of the meter deal in this group.
So if you right click on a material you would have user defined property group or just select here.
Then you have three different options.
One you can add a function which is analytic you can use interpolation where you give the setup points
and into interpolate.
You can also add piece face function for example 0 to 1.
It's linear 1 to 2 x parabolic and so on.
You just have to click on one of the function and you write the expression and the argument.
Similarly if you want to do some kind of interpolation it give the value of T and F of T and interpolation
method and you will go to.
Also you can use piece face function.
For example you give the start and end point and the function you can add one more you can add multiple
lines to have a piece Y's function.
So I assume you with an example suppose from minus 1 to 1 I have X from 1 to 2.
I have 3 x and so on.
So if a plot you see from minus 1 to 1 I have X from 1 to 2 have 3 or something like that and then you
have to use this function in terms of your property in the material that I am not going to cover in
this course because that is totally a different thing.
It will take probably many hours to go through that.
So in this course I am not going to talk about how to use my tools in a simulation how to use user defined
group and all these things that I do in 0 later of course.
Anyway let's move on.
So I hope this is clear for you.
The property group is used mainly for user defined properties.
Just remember that and there were people and also let me discuss about the user defined liability what
each user defined liability as the term suggests.
Suppose you create a material with a lot of properties or whatever is important to you.
You rename the model liability and then you can always add to user defined liability.
So when you click on add material at the bottom you have user defined library and inside that it you
will have all the materials in the user defined library.
Okay I hope this is clear to you.
Let me recap what I have taught in the Maitreya series in the first section.
You have the material you can add blank already made material which is a lower income so in the second
video I discuss about the property group where you can use their own function to define your own property
and then add that which will in your library.
So this is the overall idea of the material window in comes metaphysics here I end the Section 4 matrix
in my next section I'll talk about the physics incomes and metaphysics.
That would be interesting too.
Goodbye.
Take care and I'll see you in my next video.
