Such a question cannot be answered. We need to know your case and the experiments you did by curing the exception.

Hi, Sr

I am going to tell my study,

I am studing on a m,cro pulsating heat pipe (I have attached), I have also shared my mesh picture,
I used transient VOF solution, hallf of pipe filled with water and other half air.

time step is really too small like 0.00001

but some time I have written, program giving me floating error.
