X domain showing negative
 

Hi.
I meshed my model and found that my X(min) domain is extending to -6.81316e-18. Though i made my model in design modeller where i selected the origin.
I have two queries. How to make it 0. and second thing can this be the reason of error AMG solver divergence:temperature.
I am unable to run a single iteration
My geometry is symmetrical about x axis

thanks
