Hello everyone,
I would like to know the way in which I can simulate the metal block that will be falling down. How to make an object motion falling due to gravity using the CFX? And what model is to be used for the melting of that block?

You need a 6-DOF approach for the block with deforming meshes in the fluid. I would suggest to use fluent for this.

Hello Gert-Jan,
So should I make the fluid first and then punch a block like hole in it? Or two separate bodies of fluid and block have to be created?

Before asking us a lot of questions, you should ask yourself: What EXACT question are you trying to answer when doing CFD on this very complicated process?
Then we might be able to help you with setting up dedicated CFD-setups.
And don't say that you have been told to do CFD on this process. Because then you're lost.

I wanted know how to approach this process. I searched for tutorials but there are no any tutorials available for such problem. Just like to know whether ANSYS shows exact melting of the blocks like changing the shape of block or it just shows only temperature changes in block and not the shape.

Probably you won't find tutorials on this process since it way to difficult for just a show case. Start to sum up what you need: multiphase with 3 phases (gas, liquid, solid), combustion, 6-DOF for the block, deforming mesh since it is falling. Melting, etc.

If you would have some experience on CFD then you would know that you are asking extremely difficult things. As a CFD-beginner, I would start as simple as it can get, and then add more and more physics. Maybe you'll get somewhere. And reach your final goal in 5-10 years time. If you are very determined.
