Well turns out my guess was right... one cell thick meshes don't work. Now it's just a question of how little cells can one put across the thickness. It's curious to see that all vertexes got mapped properly, I'd expect for the outermost ones not to be and I was ready to attribute that to the...
The shape of the map can be understood simply,
At high revs the BSFC is high (low efficiency) because the mechanical losses are high.
Under low load the BSFC is high because the mechanical efficiency is low (mechanical losses high relative to work produced) (this is worst for gasoline because...
I only have one solid part, I tried splitting the surface but the error persists and the elements that don't get mapped are the same, I then tried to refine the solid mesh (making it the same size of the fluid mesh) but got the same error.
Do you know if the fluid region needs to surround...
Hi Romain,
Were you able to solve your problem? I'm getting the same error, I've structured the Input file based on the tutorial that comes with STAR-CCM+ (which runs fine).
Regard's,
Pedro.
i forgot one thing, i think the helical camshaft would be very unpratical if not impossible for this aplication, its a direct acting (bucket) system so the contact path is probably to wide.
well facty just answered the question for me... i just want to add that if one is to be called an engineer one must be an engineer and not just some guy that spend 3 or more years in the university, thats what i think.
Greg he talks of hiting a bump while cornering, i posted the website to show where he aplied the loads.
This is not my area of strength (i dont have one in fact). making a model of the buggy's suspension in working model or some similar software and them droping it and measure forces that...
forces that actuate on the tire under driving, like lateral acceleration, braking, acceleration, bumps etc

SomptingGuy, the objective is to race the car in 2011 so having everything ready for testing and training in the beginnings of 2010 would be nice.
larrylcoyle, i believe the new profile will have less duration and since the original one must be agressive ish... but i may be wrong we haven't...
Ok, one more question, what kind of data does a grinding machine needs? i have expressed the shape of the cam in cartesian coordinates about the center of the base circle
larry, i think theres no rules about head porting but there's rules about outside services, it must be a student project... i would consider partnering after i see the results of what im doing, i live in Portugal so i dot know how many people are developing (in a serious way) camshafts.
