** ERROR 99466 ** The composite Poisson's ratio value (v23) is not physically possible given the other mechanical property coefficients. Actual v23 value: poissons ratio value Maximum v23 value (1-2*E2*v12*v12/E1): reference value. Check the material data and run the analysis again.
The composite (matrix+fibers) Poisson's ratio values (v12 and v23) specified in the mechanical properties of the currently selected material describe a material which expands when it is compressed. This is an error.
