HELP：error ：Floating point error: invalid number when i drag coefficient udf was used

I'm modeling gas-liquid two phase flow with eulerian model, at the beginning ,the simulation goes well,but when i load a drag coefficient, there is an error after about 50 steps calculation :
Floating point error: invalid number
Error Object: ()
I've tried to decrease the under relax factor, it seems not useful.what should i do?
Thank you for your answer in advance

Initiating the case with wrong conditions may lead to floating point error when the iterations start.
and also wrong boundary condition definition might cause the floating point error
