Hello guys,
so basically I would like to do the melting simulation using ANSYS Fluent.
I will tell you my goals and my boundary conditions that I have set in the ANSYS.

My goals its pretty simple,
I just want to know in what time the solder ball will melt, and how the shape when it's melted in 60 seconds.

And here is my boundary conditions :
I have 3 parts, the biggest one is heater which produce the constant heat (523 K) from the bottom surface and goes up.
The thin plate above the heater is the copper plate which has 3.2 mm thickness.
And the small ball is the main guest star. The solder ball which has 0.76 mm diameter.

And here is my simulation result (condition) :
- I do the 2 dimension transient simulation in 60 seconds.
- The heat transfer is there, but there is no deformation due to the increase of temperature in solder ball (the solder ball doesn't melted)

 

I attach my simulation picture below :

What happened to the other thread on this? Why do you expect the ball to change shape?

Which licence are you using? May need to check the first few lines of the file to figure out what's going on. 

[akudjien]

Yeah, based on the experiment the solder ball is melting (change of shape) but it's not happened

[Rob]

What models did you switch on to allow movement?  Still need the licence details. 

[akudjien]

what "models" means?
so sorry, I hasn't being a master in ANSYS yet. lol.

so,basically what I did is right or how?

[Rob]

I don't know: what did you turn on to make the solder move? 

[akudjien]

Hmmmm do you mean "the solder move" is changes in shape?

[akudjien]

I only turned on the meltin&solidification, energy, and also the multiphase - Volume of fluid

[akudjien]

and what do you mean the lesson details?

[Rob]

Licence details: it'll help figure out what (and how much) you can model regarding mesh. 

OK. Go through the tutorials to understand what's going on: you won't see any change in the solder shape in the current model.

License details : Hmmm..how can I know about license detail it self?

Tutorials : Hmmm..and also where is the source so I can see the tutorial as you said?

[Rob]

Tutorials are found in from the "Help" button in the software in R19.x & 2019Rx there's usually a melting/solidification tutorial in there. 

The licence file will most likely be in 

C:Program FilesANSYS IncShared FilesLicensing

If not, open the licence manager (it'll be in the Start Menu) and find the file in there.
