Hi alinik, the main problem is that when the valves fully shut some parts of the geometry change and are automatically renamed. So CFX can not address the boundary conditions defined at CFX-Pre to...

As Murphy says: if something can go wrong it will... I normally use a computer with Ansys 14.5 Academic, which has this option. Yesterday I spent the whole day searching for this option in a...

I am trying the second option and I'm in doubt in how to switch the interface on and off. I created a simple example of a small cylinder in one domain connected to another in...

Hi, I tried to implement my moving mesh algorithm to the valves in an engine model where only the valves move and the piston is at BDC. So I forced a mass flow at the inlet, with the intake valve...

I checked the named boundaries again but it was ok, so I changed my strategy. Instead of tracking the position of the valve and remeshing while...

I followed your advice and tried now to model only the valve motion, as seen in the picture. I set two opening boundary conditions, so air can enter or leave the domain as...

Hi again, I tried to do some simulations of the intake (domain with only the intake pipe and valve) and model the valve motion tracking the valve position and using remesh. After the second...

Hi, thank you very much for the answer and for your thesis. I will read it carefully. And yes, I am not modelling the entire manifold, but only parts of the inlet and outlet pipes. I know it...

Replies: 21 Modeling the air flow of an Internal Combustion Engine Views: 7,335 Posted By mateusdias89 Modeling the air flow of an Internal Combustion Engine Hello, I am starting to model the air flow in an internal combustion engine and started now to work on the moving parts. I divided this task in two parts: In the first, I want to learn how to...
