    i failed to move the solid float through the pipe with velocity.how i can define the solid float in comsol? when i will give flow at bottom then how i can simulate the float to change the height. i have the necessary equation but i failed how i can change the position of the float??

    its urgent please help....

    Your image uploads did not appear to work. I think for images, they need to be hosted on a website and linked to with the image tags. Maybe try uploading them as attachments instead...
