I have a fluid domain of 20 mm in length and 16 mm in the breath which has a 12.53 mm pipe (circle for 2D) in the enter. From the top of the fluid domain, a 2 mm inlet is provided. The pipe is a heat source expected to evaporate 5% ethanol-water mixture. The operating condition in the fluid domain is 30 torr and 30 deg C. I tried with creating symmetry at the centre but I get a floating-point exception. The simulation is similar to a falling tube evaporator. I would really appreciate help for the same. I have attached the image of geometry and the script.
