Corona considerations


Depending on the particular geometry, a too dense mesh could be necessary in order to achieve a convergent result in the breakdown power threshold. This situation could then lead to a memory overflow, which ultimately would fix the limit in the results' accuracy.


Errors can occur when importing the EM fields. Considering a mesh too dense,  a memory overflow could occur in the numerical simulation. When this happens, a coarser mesh for the EM fields should be taken, even though this could lead to a loss of accuracy.

Alternatively, the user can focus the simulation on regions of analysis specified inside the device (see Specifying Regions tutorial). This way, the mesh used in the computation is still dense, so that the accuracy is maintained, but a memory overflow is avoided.
