.inp

Analysis input file. It is read when the analysis, data check, and parameter check options are selected. When you submit a job associated with a model for analysis, ABAQUS/CAE first generates an input file representing your model and then ABAQUS/Standard or ABAQUS/Explicit performs the analysis using the contents of this file. Alternatively, you can ask ABAQUS/CAE to generate only the input file; ABAQUS/CAE writes the input file in ASCII format, and you can view and edit it in your working directory or If you know the rules you can write your simulation input file directly without creating .cae simulation file.
