Hi everyone,<\/p>\n

I want to simulate the mechanical behavior of soil with ansys apdl. I have defined the properities of the porous elasticity and the modified cam-clay material according to the help file as:<\/p>\n

! Porous elasticity<\/span>
Kappa = 0.0024<\/span>
NU0    = 0.279<\/span>
pt_el = 5.835<\/span>
E0    = 0.34 <\/span>

Mc       = 1.24<\/span>
a0       = 35<\/span>
ah_min   = 0.35<\/span>
Beta_Dry = 1<\/span>
Beta_Wet = 1 <\/span>

TBDATA,1, Lambda_F, Mc, a0, ah_min  <\/span>
TBDATA,5, Beta_Dry, Beta_Wet, Ks<\/span><\/p>\n

 <\/p>\n

However, when I checked the tblist, only the tabular data of the cam-clay material exists. In addition, when I run the analysis, it gives a warning about the missing data of the poisson’s ratio.<\/p>\n
