hello,everynoe I did a 3D model for solute transport a few days ago ,and it ran well. However I ran it again today and found that I was getting an error:

No consistent initial value found Unable to read or write to extra nuclear files The last time step does not converge

It is clear that there is no problem when running for the first time. The two models are set exactly the same. I don’t know where the problem is. Can someone help me?
