Maxwell 3D - DC analysis on Human Body

Click For Summary
SUMMARY

The discussion focuses on conducting DC analysis using Maxwell 3D on a human body model. The user encountered a warning regarding geometry stitching and terminal surface mesh fitting issues with various body components, including the skull, skin, and muscles. The successful completion of the simulation was noted, but the warnings indicate potential inaccuracies in the results. The recommendation is to establish an equivalent circuit for the human body to improve simulation accuracy.

Hi,

I am using a Human body model which I built for some simulation studies.

I was trying to pass DC current through the Human body and though my Project completed the simulation successfully I got the below warning message. Can anyone please help me interpret it?

The error log is as below:

[warning] Geometry stitch failed. Falling back to backup process (7:59:16 PM Jul 19, 2013)
[warning] Terminal surface mesh does not fit with conduction path in the following bodies {VHP_Skull,VHP_Skin,VHP_Fat,VHP_Muscle,VHP_CSF,VHP_Brain,VHP_Jaw,VHP_Ribs,VHP_Lungs,VHP_Aorta}. Please verify them to ensure no bad effect on solutions! (5:04:16 AM Jul 20, 2013)
[info] Normal completion of simulation on server: Local Machine. (6:18:46 AM Jul 20, 2013)
