​​​​​​​I am working on impactor hitting the masonry wall. I want to apply the interaction property between the impactor surface and wall. I have created Surface to Node contact interaction, thereafter I am getting the following error when I am submitting the file for job. Interaction property is not available in an ABAQUS/Explicit Analysis. The input file was not generated, and the job was not submitted for analysis.
