FLUENT Erosion DPM (Methane with Sand) - Strange Erosion Contours

I intend to model sand laden flow in a pipe of a certain complex geometry, and have more less followed the tutorial here (www.cfluid.com/batch.download.php?aid=642) except with a different erosion correlation (Det Norske Veritas's) and with a different flow condition of methane gas instead of water. The computed velocity flow field seemed fine.
Below are the velocity contours and the erosion contours I computed, of which the erosion contours are obviously wrong (negative erosion? ). However, I am unable to find the problem with my simulation and hope that someone here can enlighten me.
Many thanks in advance.

Can you show us the correlation you used and specify which parameters did you input in the wall boundary conditions for walls?Probably the problem is there (equation or units).
Google is your friend and the same for the search button!

If I have 2 phases
-Primary Phase - water
-Secondary Phase - CaCO3
Can Accretion Model simulate the particle or granular of CaCO3 deposit to the wall which the excessive CaCO3 enough to block primary phase and cause clogging ?
You can see my attachment for explanation.
