NaN/Inf error in flui flow with k-epsilon

I was wondering if someone can provide some insight on an error that my simulation keeps
repeating:
Undefined value found.
- Detail: Undefined value found in the constraint residual vector.: NaN or Inf in vector.
I am simulating a backstep with k-epsilon turbulence model that I modified to a Low Reynolds K-Epsilon.
Can anyone give some advice on how to overcome the numerical limitation?
Maybe the Vanka preconditioner as stated in the manual?
But I am not sure how to implement it...the information on the manual is scarce on this subject....
I have attached the file for better understanding.
Best Regards,
Rui Silva
