problem with divergency of diesel injection
 
Hello every body,
when I use DPM with diesel fuel injection and pressure swirl injector. I see this message when injection is started :

Time step too small in stiffbs:

after several injection I see the message "turbulence viscosity ratio is more that 1.00 e5"

and problem diverged. Hoe could I solve the problem?
thank you
