taxalian is on a distinguished road
I am trying to run the test case i.e. DTMB 5415 to see the wave formation and resistance prediction. I am using OF 2.2.0 version together with the LTSInterfoam. As a template i used the setup already defined in the wigley hull tutorial.
But i am having convergence problem with this test case and following is the attached error for my test case:
