Hello experts
I am simulating a 1-degree cylinder's movement in the open channel and waves by dynamic mesh. when I simulate 6dof by layering and defining cylinder movement by UDF and waves by use of Fluent modules, everything works correctly, however, when I represent waves by UDF and I compile 2 UDF after 3 seconds of simulation I faced the below error, does anyone have any Idea?
do you think it is because of meshing? if yes why was no error encountered in the first case when I define wave by fluent module?
