Before running the simulation, we can click the "Check" button.
The "Error Checking and Diagnostics" window will show information about the simulation
as well as eventual warnings and errors.
In our case, we have no warning so we can proceed with running the simulation.
Once the simulation has been run, data is stored in the monitors and the simulation
is in analysis mode, meaning we cannot modify the simulation settings or the geometry.
To be able to apply any modification, we need to switch back to layout mode.
For example, let’s say we want to add a mesh constraint to reduce the mesh size at
the surface of the particle, and more accurately resolve the locations of the metal interface.
We switch to layout mode, add the mesh constraint object and edit its properties.
We set the maximum edge length to 15nm, the surface type to solid and select the "particle"
The "outer surface only" box is checked so the mesh constraint applies to the surface
of the sphere only.
We can now run the simulation again.
In the next unit, we will analyze the simulation results.
