My runs always fail with the error Floating point exception error, I’m running an incompressible so the pressure can be 0. The kinetic energy is non 0. I have no idea how to fix this error. It says to make the timestep small but I can’t find where to do that. Here is my project: https://www.simscal…

Hi there, in case of this error, please refer to the following two pages: Error: Floating Point Exception | SimScale Knowledge Base Most Popular Errors of Simulation - #3 by jprobst Best regards, Fillia

I just found it: Under Simulation Advanced Concepts Simulation Control Delta T (You have it set to 1s)

What is it suppose to be set as?

I tried it, non of the solutions helped.

Hi there, which approaches did you try?

I made sure my pressure wasn’t set to 0 can you check my simulation for me? thanks!

Hi there, have you checked the second link I sent you? There are many approaches listed there, make sure to try these :slight_smile: I am posting it again: Most Popular Errors of Simulation - #3 by jprobst Cheers!
