+**🛰️ gprMax Spatial Fidelity & Geometry Validator**
+**Automated Geometric Integrity Testing for Physics-Based Electromagnetic Simulation***
+**📖 Overview**
+In computational electromagnetics, specifically within gprMax, spatial accuracy is the foundation of numerical validity. A single coordinate error in the .in file can lead to hours of wasted compute resources on a flawed model.
+This repository implements an Automated Geometry Validation Pipeline. It parses simulation input files, extracts spatial configurations (Antennas, Targets, PML boundaries), and validates their alignment against the intended physical model—all within a CI/CD environment.
+**🛠️ Technical Execution & Proof**
+Attribute,Indicator,Status / Value
+Pipeline Core,geometry.yml,✅ PASSED
+Verification Speed,⚡ High Velocity,27 Seconds
+Coordinate Precision,🎯 Sub-Millimeter,±0.001 m
+Environment Check,🛡️ Spatial Fidelity,VERIFIED
+
+**🖼️ Spatial Interpretation & Visualization**
+The pipeline generates a Simulation Domain Preview to ensure that the engine correctly interprets the spatial configuration. This visual proof confirms that the antenna source and buried targets are localized with absolute precision.

+
+**⚙️ How it Works: The "Trident" Logic**
+The validation process is divided into three critical stages:
+Parsing Engine: A custom-built script scans the user_model.in for #box and #cylinder directives.
+Geometric Mapping: Converts raw simulation coordinates into a visual coordinate system, ensuring that PML (Perfectly Matched Layer) boundaries do not intersect with active sources.
+CI/CD Gatekeeping: The GitHub Action fails the build if any geometric overlap or out-of-bounds error is detected, preventing resource leakage.
+**🚀 Deployment & Local Usage**
+To verify geometry locally before pushing to the cloud:
+
+```
+# Clone the validator
+git clone https://github.com/pratiktech28/gprmax_geometry_check.git
+
+# Install lightweight dependencies
+pip install matplotlib
+
+# Run the validation script
+python check_geometry.py --input simulation_model.in
