Dear group,
I try to model parachute opening process. for modeling , I use UDF and Movig Meshin fluent. I had correct answer in steady state but in unsteady state, when canopy of parachute is translate, answer is incorrect.
I use pressure on face to translate canopy in UDF, after that, I use moving mesh. My model has unstructured mesh. Problem is here, when I pass 2 or 3 time steps, I observe one layer of low pressure near of canopy. ( and path line has mistake )
I get one picture about my problem.
