For the case study of the radiation usually there will be all different phenomenon or different situation in the working principle itself because the radiation there, there won't be any medium, right. So we have to create a model like that. So, here we are just taking our rock model. So what we can do is take our small circle and so this is going to be our model. Let's take the unit's into mmm this time and extraordin so turkey Mmm. So Tonto And create it again.

So, okay. So, that is not exactly at the center business is going to be our model extrude so, that is no far if you want to observe the residuals carefully just take 15 mm then generate here you can see I have created two models This is one this is to two solids. So, here you can see the gap between these two bodies and this is going to be our heat source and due to that heat source, so, we are going to see how it is going to affected right so, let's Get into the measure so doubletap on the measure. So, since it is the radiation, the effect what we are going to see on the other body will be very minute unless and until there is all very huge temperature from this hole, right. So let's wait and see what is going to happen with that.

So just generate a normal mesh. So so this is the mesh what we got. So the temperature source will be this one and take the whole body and give it more temperature. I'm just giving up 5000 degrees centigrade and And the phenomenon is the radiation. So, just select the radiation. Here you can see the German trees.

So, what we can do is So, you just select by holding CTRL select these two phases, because this is the phase where the radiation is going to emit, and this is the phase where the radiation is going to be observed. You can see the green tick mark here. If you have given the right condition or not by seeing here we can click and here you can see the type and here So, the correlation Here we are using surface to surface So, use surface to surface correlation And so, hear me CBT you can see the one that is the perfect body that is a perfect body constant that is and if you don't know anything you can here simply you can go here you can go to Tableau data. So, we are not using any tabular data here. So, so, just what we can do is just keep it constant or emissivity just to give it as one that would be fine.

So, once we have with that, so, here are the results will be same, but we can see the temperature effects here. So let's solve the problem
