Having trouble getting a circle to fall through water
I'm trying to get a circle to fall through air into water where it will float. I am creating my mesh using ANSYS Workbench (which I have to use) and exporting it as a .msh file. I then start up FLUENT, load the mesh file and set up the system in the same way as a tutorial I have done which had a falling box. However I get major problems with mine as you can see in the pictures attached.
The only difference I can see (apart from it being a circle instead of a box) is that in the tutorial their box was inside a slightly bigger box and they fell together but if my understanding is correct I shouldn't need that second box. I tried to create it but I'm not good at using design modeler and couldn't get it to put circle inside a box inside a box without it subtracting the area between the circle and the smaller box.
Can anyone see what I'm doing wrong and is there anymore info you need to help?
