Can't view cracking/crushing of my solid65 elements

(OP)
Hi

http://ansysx.blogspot.com/2011/03/crackcrush.html
You can find the picture of what i want to do in the above link.

I am modelling a concrete wall using SOLID65 brick elements. the wall is fixed to in all 6 DOFs. I am applying a pressure load to the face of an element in the surface of the wall.
i want to plot the crack/crush of the concrete elements. but can't, this is what i am doing.


Material Properties:
I have defined;
1- the elastic properties,
2- the multi-linear properties of the concrete using 7 stress-strain points.
3- density
4- Concrete properties (which can be found under: MATERIAL MODELS> STRUCTURAL> NONLINEAR > INELASTIC> NON-METAL PLASTICITY> CONCRETE).

Solution Controls:
1- static analysis
2- Time Control: Number of substeps 50
3- Frequency: Write every substep.

General PostProcessor:
1- Turned on wireframe in (PLOTCTRLS>DEVICE OPTIONS)
2- Under (PLOTCRTLS>HIDDEN-LINES OPTIONS> TYPE OF PLOT) used Non-hidden
3- When Plotting the concrete crack/crush in (PLOT RESULTS>CONCRETE PLOT>CRACK>CRUSH) there is no representation of the cracks

What am I doing wrong!!!
