ABAQUS is a finite element analysis (FEA) software that can be used to model the behavior of various materials, including mortar. In order to accurately model the mortar volume in ABAQUS, the following steps should be followed:

Overall, the key to accurately modeling the mortar volume in ABAQUS is to carefully consider the material properties and boundary conditions, and to use an appropriate mesh size to capture the behavior of the mortar. In addition, it is important to verify the accuracy of the model and the results using appropriate validation techniques.
