Solidification
 
Hi

I have used Ansys fluent to analyze the centrifuge casting[ it is a method in which it produces solid cylinders opposite to centrifugal casting].

Here i used a simple jar which is kept at vertical and the molten metal is poured at the velocity of 0.01 to the inlet. and i used transient state, meshing having good quality about .001 skewness.

Solution method SIMPLE is used and all other parameters at second order [energy, turbulence..] and also i given a 200rpm of rotation to the jar.

The problem is when i run the calculation for Time-step .001 for fixed time,
i got results of solidification for .01 seconds but as i increased the time the solidification is not happening, it shows more fractions of liquid in the Jar.

Please help me here .....
