BioMOR

This directory contains a code based on FFT and Model Order Reduction for the parametruc analysis of electromagnetic fields and voxel-based human body interaction

---

Description

• "FFT_SingleSolution.m" solves a single problem with a frequency value and nominal resistivity
• "FFT_MORfreq.m" generates a Reduced Order Model (ROM) with frequency as parameter
• "FFT_MORres.m" generates a Reduced Order Model (ROM) with resistivity as parameter

All user-settable quantities, e.g. frequency, are contained in the block identified by the BEGIN USER SETTINGS / END USER SETTINGS comments.

Available test cases

A simple test case is contained in separate directories under the folder "data". Set the "name_dir" variable in "FFT_SingleSolution.m", "FFT_MORfreq.m", "FFT_MORres.m" to the appropriate directory.

User-defined test cases

Follow the instuctions given in "README.txt" inside the "data" directory.

Results and Visualization

In the "res_para" directory, the results generated by "FFT_SingleSolution.m", "FFT_MORfreq.m", "FFT_MORres.m" are exported in Paraview format. The Reduced Order Models can be used as shown in the "USE MOR" sections of "FFT_MORfreq.m" and "FFT_MORres.m"
