============================================================  1. Project Description  ============================================================  This dataset was generated as part of the PRELUDIUM 20 research project (NCN Project No. 2021/41/N/NZ9/02874).  The main goal of the study was to develop finite element models (FEM) of tissue and whole fruit of the 'Chopin' apple variety at various ripening stages. The aim was to predict mechanical material behavior based on the physiological condition of the fruit.  

Although the project originally focused solely on 'Chopin' apples, comparisons with other modeling approaches and methods were also carried out during the course of the research.  

============================================================  2. Dataset Content and Structure  ============================================================  The dataset contains experimental and modeling results organized into structured folders. Each folder reflects a particular type of analysis or visualization.  

The dataset includes the following types of data:  

1. FEM Modeling Results (ABAQUS)     - Graphical outputs of FEM simulations (CPress, Mises stress)     - Static images (.jpg) and animations (.avi) of stress distributions  

2. Micro-CT Imaging Results     - Cross-sections of apple fruits with visible internal damage     - Image formats include .jpg, .png, and .bmp  

3. Graphic Project Files     - Editable layered project files saved in .xcf format (GIMP) for most graphics  

4. Summary of Experimental Results     - Excel file titled "PRELUDIUM MAIN RESULTS" summarizing key findings and data  

============================================================  3. File Formats  ============================================================  The dataset includes the following file formats:  - .jpg, .png, .bmp – image files from FEM and micro-CT results  - .avi – animation/video output of FEM simulations  - .xcf – layered graphic projects (GIMP source files)  - .xlsx – summarized experimental results  

============================================================  4. Usage Instructions  ============================================================  - Image and video files can be viewed using standard image and media players.  - .xcf files can be opened and edited using GIMP (GNU Image Manipulation Program).  - The Excel summary file provides an overview of the most important results and can be used for analysis or further processing.
