extension for liquid fraction contours
 

Haai, I am doing solidification model. i am trying to animate the liquid fraction contours by using execute commands. if am writing command as "display set hard-copy vel%t.tiff", i can get the velocity contours, and for temp%t.tiff, I can get temperature contours. But what extension I have to give (before %t.tiff) for getting liquid fraction contours? I want the extension to get liquid fraction contours like XXXX%t.tiff, I WANT TO KNOW XXXX FOR LIQUID FRACTION CONTOURS IN SOLIDIFICATION. If any body knows about this please send me information as early as possible. Thank you
