Hi,
Open Abaqus/CAE and go to File -> Import Model. In the menu that pops up change the File Filter Type to "Abaqus Input File (*.inp,*.pes)". Navigate to the folder where you stored your .inp file, select it and press OK. Abaqus/CAE should read your input file and recreate the model in v6.10.
Read "Section 10.8: Importing a Model" in the Abaqus/CAE manual for more info.
Good luck,
Dave
