Error in Abaqus

[Krsl]

Hi all! Why am I receiving this error message? Can anyone please help me how to eliminate this error? I have also attached the Concrete tension and compression properties herewith.

Failed to regularize material data for material CONCRETE. Please check your input data to see if they meet both criteria as explained in "MATERIAL DATA DEFINITION" section of Abaqus Analysis User Manual. In general, regularization is more difficult if the smallest interval defined by the user is small compared to the range of the independent variable.

shouldn't the stress-strain curves start at 0,0?

and the tensile data is monotonically decreasing in stress ???

and the tensile data uses displacement and the compressive data uses strain, ???

Try following the advice from this thread:

But also check the documentation chapter describing the material model you are using (CDP?) - there you will see what a correct definition should look like.
