Hi,
I a modeling a time dependent mass transfer from a sphere into a fluid flowing past it in a cylindrical pipe.
Now when I am measuring the concentration at a particular point in the fluid, initially my concentration is becoming negative.
Can you help me with why this is happening?
Please see the attachment.

Hi
Your values are practically zero, of the order of 1e-15. I would not bother. The issue of negative concentrations is repeatedly discussed in this forum. Please check them
