[FLASH-USERS] Question about star formation using FLASH

[John ZuHone]

Hello M.A.,

	Such capabilities are not currently in FLASH2 and they will not be in  
the first release of FLASH3, though they *may* be in future releases.  
Others have managed to get this working for their own use.

	Strictly speaking one would not be converting gas particles (since  
we're working with Eulerian grid variables) but would be creating  
massive star particles from scratch at a particular grid location once  
conditions were met at that location (say, density rises to a certain  
value and temperature falls below a certain value). Then the star  
particle would be taking its velocity as well from the local velocity  
on the grid.

	In essence, this is not currently implemented but once one had a  
prescription for this it should not be difficult to implement.

Best,

John Z
