Hello

I have been coding for decades starting with Moldflow in 1979.... still coding now partnering with 6 different AI tools to take my code and enhance. Way back i wrote interfaces and FEA conversion programs to inspect the quality of the models.

After seeing many issues from INP's from our partners i decided to build a few new tools for Abaqus. I share the final executable along with guided walk throughs for drop, random vibe and more. 

Below is an old posting, i am up to V24 and code exceeds 50k lines.... 

It's not to replace any Simulia product but to work alongside.... Its free and i am continuing to modify based upon feedback. 

I am not selling anything just looking to share.

Free Tool Release — Abaqus INP Comprehensive Analyzer V18.5

This tool embodies decades of hands-on CAE development and application. At 31,500 lines of code and growing, it is both a professional model review tool and a learning resource for the simulation community — and it is completely free.

What the tool does: 

It reads your Abaqus .inp file without requiring an Abaqus license and answers the questions that come up every time a simulation model crosses your desk. 

Is the unit system consistent? 

Do all parts have material assignments? 

Which node hits the floor first in a drop test? 

Where is the center of mass? 

Everything is read directly from what is already in the .inp file — no black boxes, no assumptions, fully documented.

The tool leverages the PyVista graphics engine — the same GPU-accelerated VTK-based rendering used in professional scientific visualization — to display your assembly in correct global coordinates, with interactive part selection, section cut, opacity control, and multiple orthographic views. 

What you see matches what Abaqus/CAE shows, because the coordinate transforms are identical.

Who it is for: CAE Analysts — reduce hours-long model audits to minutes 
Design Engineers — verify the simulation matches your design intent before it runs 
Program Managers — plain-language quality reports without reading Abaqus syntax

What is new in V18.5: 
Assembly coordinate transforms validated at 0.01 mm against Abaqus/CAE — every part in its correct global position across all views and all calculations 
Impact/Drop Analysis rebuilt from first principles using plane-equation geometry from the actual floor mesh 

Thread-safe architecture for mid-parse dialogs — independently reviewed by Gemini and Grok 

Learning Center expanded with Material Properties best practices and a Behind the Scenes category explaining how the tool works under the hood

The philosophy: Every number this tool reports comes directly from the mesh geometry and keywords in the .inp file. No assumptions. No black boxes. 

Transparent by design. That is what combating engineering mind blindness looks like in practice.

This tool will continue to grow in scope as both a learning and professional resource. If you would like to see a specific feature added, let me know and I will build it in.
