Open Foam is excellent and free . I use it a lot . Not easy to learn as a first introduction to a CFD package though .

Not one of mine - this comes from the SymScale Library - but it shows modelling of plastic beads being fed into a plastisicer .

Thermoforming is usually a secondary production process . Pre moulded sheets of EP are heated and pressed in dies to form generally simple shapes .

What is the actual project that you have to work on ? Edit : I see you mention hot gas diffusion but could you provide more details ?

In all the basic product making processes the chemical activity is largely finished before the shape forming process begins so I don't entirely understand the question ? Anyway the shape forming processes all involve variants of the injection moulding principle - there's lot's of information on...

Success is generated by a suitable combination of Motivation + Opportunity + Capability . It's a bit like the fire triangle - Ignition source + Fuel + Oxidiser .

What more do you need to know ? Do you want information about the practical engineering of the moulding equipment or theoretical modelling of the material flow in the moulding process ?

I am not sure how far you are going to get with this project starting from no knowledge of numerical methods , computer programming , fluid mechanics , theory of CAD/FEA/CFD or commercial analysis software and with a twit for an advisor but genuinely best of luck anyway . Not much de novo CFD...

Look here and then chase the thousands of secondary links .

This is a non steady state problem . Each team is trying to pull the other one towards it and so win the match . So as one side pulls harder the other side pulls harder until such time as one side reaches the limit of it's pulling strength and falls over or starts slipping along the ground ...

Surely the condition shown in far rhs image can never be ? The arc shaped pipe will have been tipping over in the clockwise direction continuously since the ball first entered it ?

Depends what you mean by removal . 'Delete' just moves it to the recycle bin . You or an intruder could still easily move it or open it . 'Empty contents of recycle bin' just removes the easy access option . The file - for an initial period at least - still exists on disk and can be...

That's a valid observation . So you can reasonably make the decision that it needs to be a flanged beam . That is what I would have decided on as well . Really any beam being cast directly into a concrete slab has to have features which lock into the concrete . These features occur naturally in...
