Currently, I am working on my Final Year Project 2, designing a harvesting raindrop energy system using piezoelectric. I am using Ansys to analyse the amount of energy able to be harvested from a raindrop diameter range from 0.5 to 6.0 mm on a single piezoelectric

I am using two YouTube videos as my guide for my project, however, I am facing issues and am not able to proceed according to the video.
Flow-Induced Vibration of Piezoelectric Energy Harvester using Ansys Workbench for the setup of the analyse and Ansys CFD droplet 水滴下落 for the setup of the raindrop

The issue that I have for now is when running the calculation, it is only able to process the first step and has the error of Floating Point Exception. Sadly, despite this question occurring in the forum, it doesn't provide any help despite I had checked my mesh quality, boundary conditions and models. I am not aware which part goes wrong

How did you initialise the model? VOF for rain droplets may be a little ambitious. How is liquid entering the modelled domain?

Dear Rob,

I created a region through Region Register, I saved a sphere a raindrop with coordinates and radius.

After Initialize in Initialization, I Patch... by selecting Water for Phase, Volume Fraction for Variable, Value equal 1 and region_0 for Registers to Patch

That's fine. How many cells across the droplet diameter?
