hi everyone

i want to simulate motion an object in the 2D in rectangular channel(plan)

this motion involves: 1-transiation motion 2- rotation motion

actually the flow filed should move the object in your manner(number of degree of freedom is determined later)
For modeling and simulating this my project i need a UDF code to move the object by flow filed .

After all this, my problem is writing part of udf (force calculation in the surface of the box)

if anyone can help me comment here or contact with me by hossein.holee@gmail.com

best regards
