i am doing ic engine simulation, for that i am using cone injection type in dpm model, in that cone injection setting , how to set x-axis, y-axis and z-axis?

i have the x,y,z co-ordinate values

[Amine Ben Hadj Ali]

It should be the rotational axis of your cone. You should know that n

Dear DRamine;n i have x,y, z coordinates with we can find that x, y, z components of vector defining the cone axis?n

[veera]

pls tell me sirn

It's the direction of the spray axis. You have a point and vector, ie where the spray starts and which direction it's heading in: you need to work these out. n

I HAVE THE WHERE THE POINT STARTS , THAT MEANS WITH THAT CO-ORDINATES VALUES , HOW TO FIND THE DIRECTION?n

If the injection is parallel to the x-axis the vector would be 1 0 0 if aligned with z it's 0 0 1 You need to decide on the direction vector and then work it out: this is why you did trigonometry at school. n
