Amiya Prakash Das gave more information on the question:
This 1500 kPa is only one case; even for smaller sigmaiso < 60 kPa, void
ratio are fairly constant for each condition with capillarity. But when
i am doing shearing, the model works perfect.

>From my experience in doing experiments i can say that, in pendular
regime where degree of saturation is very low, yield stress is
independent of matric suction (even for different void ratios) but, over
there the imposed matric suctions are very high in order of several kPa.

So, what i infer is that the definition of matric suction in soil
mechanics in totally different from the capillary pressure (which is an
excess pressure due to air and water phase)....i might be wrong also in
thinking and deducing such conclusions, but physical meaning of both the
terms are different, i reckon. As, i am from soil mechanics back ground
my definitions seem contrary (which i agree...) and more appropriate
representation of the results should be in term of degree of saturation
and water content (as presented in literature for capillary model using
YADE).

Since, i am very new to this YADE so want to make sure that my
understanding is correct. Any help is appreciable.

Thanks
