FDTD Matrix

[akotowski]

The model in the CSX display shows objects at high resolution overlaid on the grid.
1.) How is the matrix for the FDTD simulation generated?
2.) Is there any anti-aliasing?
3.) Is the mass of the objects conserved?
4.) Is it possible to view the objects at actual resolution?
Thanks for your help

You can view the discretized model using the Debug PEC option.

There is a similar option for exporting dielectric materials. I can't find it in the online docs, but if you explore the runOpenEMS function in MATLAB the info there.

Both export data to view in paraView

Thank you.

The options are:
openEMS_opts = '--debug-PEC --debug-material --no-simulation';
RunOpenEMS( Sim_Path, Sim_CSX, openEMS_opts );

When I run this code and view the PEC dump I see the 'metal' shapes. I also have a 'water' object.
When I view the material dump I see the outline of the simulation box, but nothing inside.
The water object is clearly there both from AppCSXCAD and from viewing the simulation results

Any suggestions?

You will need to use paraView to visualise. Also, as the material is a volumetric solid, you will probably need to do some section cuts of the data to see inside.

Thanks, that worked. I had to see inside the box.
