That’s right. Sorry sir. I added UDF for compressible water but forgot to connect it in the water material.

I did this, I took the UDF for compressible water from the tutorial and connected it.

But now I get the solution stopping almost immediately due to errors FLOATING POINT EXEPTION #f


  1. I tried to play with the URF coefficients 
  2. Make the time step smaller
  3. I checked the grid, one is very good


This may be due to the rapid change in water density. We need to limit this somehow. There was a mention of this in the tutorial, but it was not indicated how to do it.


What’s the matter? Thank you.
