axi-symmetric mesh of dieselFoam

Hi

I made a axi-symmetric blockMesh,it produce mesh well,but when I run dieselfoam it generate an error like this:

FOAM aborting

Aborted

I know it is related to position of injetor (0,0,0) but I don't know how can I set it in 2D axi-symmetric case(injectorproperties) for dieselfoam?
I attached blockMesh dictionary of axi-symmetric case
please help me.

thanks

axi-symmetric mesh
 
Hello to all

I solved my last problem and set injector position in a correct place,now dieselfoam is run but my results are incorrect.
I want you to look at my mesh and see is this a correct axi-symmetric mesh or no?

please guide me.

Thanks
