Please can someone help me with my model?
I have attached my
and it is showing some odd activity on the right boundary. The boundary is set as open (444) but there seems to be some odd instabilities on the right side of the domain that start around step 1500 and increase to a maximum about step 2000.
I have checked the CFL number and it is around 0.25 and I've also tried changing the free surface gradient compatibility but it hasn't helped.
Has anyone encountered this before or know how to fix it?
Thanks.
