parcels too small?

Smed · March 19, 2013, 11:39

I'm using the sprayFoam solver in OF 2.1.1 to inject liquid water in a small steam space. If I set the parcel diameter at 0.001 m, the solution converges without problems. If I start to decrease the diameter (10^-6 or less), I begin to get warnings and my results become junk.

attempt to use janafThermo<EquationOfState> out of temperature range 200 -> 5000; T = 11986.2

Can anyone tell me why this happens? Is there a minimum limit on the parcel size? I've attached an example that runs into this problem.

Hello,

You might have to edit some of the constant properties in the sprayCloudProperties file namely:
minParticlemass
rhoMin
