On checking the source code faceAreaWeightAMI.c , I found out that this message appears when the magnitude of the vector indicating the normal of a particular face is less than ROOTVMSMALL( A constant with a value 1e-18). But beyond that I dont know much.
Could anyone please help me out with this? If this information is not enough, please notify me.
