** ERROR 99278 ** The required matrix mechanical properties are inconsistent. The isotropic matrix, the shear modulus is expected to follow the equation below with a relative error less than 0.1%
G12 = E1 / 2*(1+v12)
The values of parameters in the above equation are given below:
E1 = xx MPa
E2 = yy MPa
v12 = aa
G12 = zz MPa
Check the material data and run the analysis again.
The matrix mechanical property data is not consistent.
