Free surface problem

PeterGem · July 5, 2019, 03:57

Hi,

I 'm working on a project in which we want to simulate some high speed crafts in calm water conditions and during the simulation of the motorboat tutorial I faced insignificant high waves (picture below). The simulation speeds of current and air was 10 m/s. Do you have any idea how to solve the issue with the free surface ?

Hi Peter,
your picture wasn't correctly published.

I assume, you really mean they are so significant, so that they have an impact on your simulation?

Bluebase thank you for your message.

How do you define the wave for this case? Have you double checked them with the one suggested in the tutorial?

Hi HHB, I followed the instructions from the Motorboat tutorial and in my case I do not want to simulate waves but calm water conditions in different Fr.
