（先描述问题）
Hi, I am trying to model liquid spray. The calculation was fine when I model water or benzene liquid spray. But when I try to model methanol spray.
（然后给出自己的设置）
&SPEC ID='METHANOL'/
&PART ID='Particle01',
SPEC_ID='METHANOL',
DIAMETER=88.0,
MONODISPERSE=.TRUE.,
AGE=60.0,
DENSE_VOLUME_FRACTION=0.0/
&PROP ID='SprayMod01',
PART_ID='Particle01',
OFFSET=0.0,
FLOW_RATE=187.0,
FLOW_TAU=1.0,
PARTICLE_VELOCITY=42.8,
SPRAY_ANGLE=1.0,1.0/
&DEVC ID='SPRK', PROP_ID='SprayMod01', XYZ=0.0,0.0,1.0,
ORIENTATION=0.0,0.0,1.0, QUANTITY='TIME', SETPOINT=0.1/
I got the following message. Will you please help me to have a look what
went wrong with methanol calculation?
