So, I designed a paint-mixing machine which has a drum fastened to it. In real-life usage, the drum is filled with paint, and then rotates by the means of an electric motor, hence the mixing of the paint.
I would like to show this process by the simulation of the model I made. This flow simulation would show the motion of the paint within the drum while it rotates.
I am however stuck as to how to go about this
Please, urgent help is needed as I have to submit the result very soon.
