Yes, elements can be deleted from the .inp file, but it must be done carefully to preserve model integrity. Manual editing is simple for small models; scripting is recommended for large or systematic deletions.

Thankyou sir for your response. An you please shower more light on -How can we delete the elements? What is the method? How I will get to know which elements need to be deleted?

Failure modeling in Abaqus depends on the material model and failure criteria you define, not on the mesh. To enable element deletion as an option of a progressive failure model, you need to define a material model that includes damage initiation and evolution. Element deletion is then controlled by the material behavior, not something you set in the mesh module.

Even if you imported a pre-meshed model via an .inp file, you can still enable element deletion by Defining a material with appropriate damage and failure criteria (e.g., ductile damage, shear damage) amd including the *Damage Evolution keyword with the option DELETION=YES in your .inp file.

There's no need to remesh in Abaqus/CAE to enable element deletion—just modify or extend the material and step definitions in your .inp file accordingly.
