Hi.I tried to simulate a thinnest bar(or a line) rotated in a rectangular box and .The left,right,and bottom of box are no slip condition.But the top of box are free surface.I want to observe the situation about free surface. I want slove it by using moving mesh methods.Also,I want the bar rotate by the circle center on (0,0) point and it is also the endpoint of the bar.There are lots of ways Iike "rotate boundary" or'otating domain",and I tried for long time but I can't understand how it work .! (the modle is like the the problem but the bar is rotating not move horizontallyhttps://www.comsol.com/blogs/modeling-free-surfaces-in-comsol-multiphysics-with-moving-mesh/)
