[Simnibs-discuss] Head mesh not generated ( Error msg attached )

[Utkarsh Pancholi]

Hi,

I tried to make mesh generation using headreco all command in command line.
Here is the error.








*Traceback (most recent call last):  File
"C:\Users\Administrator\SimNIBS-3.2\simnibs_env\lib\site-packages\simnibs\cli\headreco.py",
line 13, in <module>    main()  File
"C:\Users\Administrator\SimNIBS-3.2\simnibs_env\lib\site-packages\simnibs\cli\headreco.py",
line 10, in main    headmodel(sys.argv)  File
"C:\Users\Administrator\SimNIBS-3.2\simnibs_env\lib\site-packages\simnibs\msh\headreco.py",
line 730, in headmodel    "Gmsh failed meshing one or more volumes.
"RuntimeError: Gmsh failed meshing one or more volumes. Please try running
headreco again increasing the '-v' option (eg. -v 1.0). Type 'headreco all
-h' for more information*

What can be done for this?

Also, I wanted to know if structural MRI images above 45 MB can be
processed without any errors as i mentioned above. But I have processed T1
weighted structural MRI image having a size of 38MB. is having the above
error.

I want to know what is the minimum criteria for the T1 weighted MRI image's
size.


Runtime error suggested increasing vertex density to 1.0. (-V).. What is
the consequence of increasing vertex density on electric field strength
distribution?

Waiting for the help.
