February 18, 2021, 18:44	Interference of UDF with flow problem solving	#1
etedalgara Member Join Date: Jan 2020 Posts: 31 Rep Power: 6	Hi. I have a dynamic mesh UDF to simulate the blade movement. I want to flow past 1 second time and after that, the UDF applies to solve the problem. all are ok with " if time >1" and the blade never moves until the time become 1 sec. but the flow diverges before time becomes 1 second! there is no movement in the test case. when I run the test case "fixed blade" without compiling the UDF all will be ok and no divergence happened! where is the problem?! Thanks for your help
