How can I correctly calculate the volume (changing in time) of a 3D Cylinder by means of a 2D-Axissymmetric modeling ?
A multiplication of the integral of the area of the 2D cross-section with Pi and with the instant maximum radius of the body might help. But even if this would work ... Then: How is the name of the appropriate "r" variable?
