This chapter discusses features related to contact and interaction modeling. It provides an overview of the following enhancements:

• “CAD-enhanced general contact in Abaqus/Standard for simulations submitted from the 3DEXPERIENCE platform,” Section 10.1

• “Supplementary vertex-to-surface contact formulation within general contact,” Section 10.2

• “Modeling exterior acoustic problems using perfectly matched layers,” Section 10.3

• “Improved domain decomposition for structural-acoustic and acoustic-acoustic tie constraints,” Section 10.4
