Alpha higher than 1 and mules implicit. -- CFD Online Discussion Forums

November 2, 2012, 22:20	Alpha higher than 1 and mules implicit.	#1
Alexpzz New Member Alessandro Join Date: Sep 2012 Location: Italy Posts: 2 Rep Power: 0	Greetings. I'm trying to simulate a three dimensional biphasic flow in microchannels. I'm using interfoam as solver, and i have the problem that the maximum value of volume fraction is higher than 1 (about 1.3). I don't know how to resolve this...Is there a way to set mules to implicit? Do i need only to change explicitSolve to implicitSolve in alphaEqn.H? I've also limited the maximum Courant number to 0.2 without significative results. Thank you.
