modified condition for splitting the model (ensembler)
modified condition for splitting the model (ensembler)

and more verbose reporting about it

The limit was 10% of the solvent content, now if the volume ratio
is known and <0.7 and the solvent content is <20%, also try to split
the model.

Because of this email from Clevermelon:
