Have been working with FLUENT and MATLAB Closely with the goal of optimizing Liquid flow paths through Aluminum bodies(i.e. Shape Optimization).

This process requires that the geometries in WB/Fluent be converted to Nodal/numerical forms for matlab processing. Up to this point I have been using Mechanical APDL INPUT & ABAQUS files exported from FLUENT for this (File>Export>Solution Data>ABAQUS).

These files provide purely text documents containing the nodal data as well as the all geometry data that can be processed in MATLAB and then re-uploaded to FLUENT for further simulation.

However when exporting these files from FLUENT I appear to lose my zone or Body Names (i.e. Fluid block_11, Aluminum Block_3,etc). Instead all zones are converted to a form of 'PID1' or 'PID45' in the text document, thus when re-uploading the geometries they lose their designated names and as all PID#. This is becoming a problem since the indexing/processing of my Fluid/Al bodies depend on their allocated name values.

How might I export these geometries in a way such that I do not use their given name values? Does anyone have experience with these file types? Or if not does anyone have a different approach to recommend?

(I have attached a visual representation of a simple 2D grid structure I am trying to work with, where each square block represents a Fluid or Al body to be determined by the optimization process)
