What is a .INP file?
INP is a finite-element input deck for Abaqus or Nastran.
- Did you know
- An INP deck tells engineering solvers the model, loads and materials to analyse.
- An INP deck uses a keyword-driven syntax in which each keyword line is followed by data lines giving nodes, elements and material tables.
- Abaqus ships translators that convert its INP keyword format to and from Nastran’s bulk-data deck, letting the two solvers swap models.
- What Analyser reads
- Identify and read more scientific, medical and engineering files: R serialized data (RDS/RData), ABIF sequencing traces, VASP/Gaussian/XCrySDen DFT structures, ChemDraw (CDX/CDXML), Axon ABF and NI TDMS instrument data, BrainVision/Neuroscan/EEGLAB EEG, Gmsh/Abaqus/Nastran/ANSYS FEA decks, SPICE netlists, VTK structured/rectilinear grids and oscilloscope waveforms.
- Depth of analysis
- .INP is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .INP file
- Drag a .INP file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
