Simulation: Solver 
Start SimulationIf you are not familiar with what the wakefield solver does and what it is used for, you should first read the Wakefield Solver Overview.
In this dialog box many important settings for a wakefield calculation run can be set. Most of them have a strong influence on the calculation time. Also an optimization run for your structure can be set up from here.
Solver settings frame
Simulated Wakelength
This settings defines the wakelength which should to be computed. It has a direct effect on the simulation time. As a rule of thumb one can assume that the simulation time doubles if the wakelength is doubled - especially for large simulations.
Store result data in cache
Check here if you want the solver results to be stored in the result data cache. The efficient usage of the result data cache is explained in the printed documentation "Advanced Topics".
Stimulation settings frame
Calculate modes only
Calculates solely the port modes of your structure, i.e., no transient solver run is performed.
Adaptive mesh refinement frame
Adaptive mesh refinement: Mark this check box to activate the adaptive mesh refinement. The mesh will be adaptively optimized by either adding extra grid lines due to the calculation of the electromagnetic field energy or by successively changing the settings of the mesh expert system. Press the Adaptive Properties... button to edit the current settings for the mesh refinement.
Start
Calculates the port modes and starts the time domain calculation.
Optimize...
This button opens a dialog box that allows you to set up and start an optimization run.
Par. Sweep...
Opens the parameter sweep dialog.
Acceleration...
Opens the acceleration dialog box to control the high performance options of the simulation run (e.g. GPU acceleration, Distributed Computing, MPI).
Specials...
This button leads to a dialog where further special settings for the solver can be made. The settings are for expert users only and should generally not be changed.
Simplify Model...
Opens the simplify model dialog.
Apply
Stores the current settings. The dialog box remains open.
Close
Closes this dialog box without performing any further action.
