=== EM.Picasso's Simulation Modes ===
EM.Picasso offers five types of Planar MoM simulations simulation modes (click on each type to learn more about it):
* '''[[#Running a Single-Frequency Planar MoM Analysis| Single-Frequency Analysis]]'''
* '''[[Parametric_Modeling,_Sweep_%26_Optimization#Running_Frequency_Sweep_Simulations_in_EM.Cube | Frequency Sweep]]''': including uniform and adaptive frequency sweeps
* '''[[Parametric_Modeling,_Sweep_%26_Optimization#Running_Parametric_Sweep_Simulations_in_EM.Cube | Parametric Sweep]]'''
* '''[[Parametric_Modeling,_Sweep_%26_Optimization#Optimization | Optimization]]'''
* '''[[Building_Reusable_Models#Running_an_HDMR_Sweep | HDMR Sweep]]'''
You can set the simulation mode from EM.Picasso's "Simulation Run Dialog". A single-frequency analysis is a single-run simulation. All the other simulation modes in the above list are considered multi-run simulations. If you run a simulation without having defined any observables, no data will be generated at the end of the simulation. In multi-run simulation modes, certain [[parameters]] are varied and a collection of simulation data files are generated. At the end of a sweep simulation, you can graph the simulation results in EM.Grid or you can animate the 3D simulation data from the navigation tree.
=== Running a Single-Frequency Planar MoM Analysis ===

A single-frequency analysis is the simplest type of EM.Picasso simulation and involves the following steps:
* Run the Planar MoM simulation engine.
* Visualize the output simulation data.
If you run a simulation without having defined any observables, no data will be generated at the end of the simulation. An analysis is a single-run simulation. In multi-run simulation modes, certain [[parameters]] are varied and a collection of simulation data are generated. At the end of a multi-run simulation, you can graph the simulation results in EM.Grid or you can animate the 3D simulation data from the navigation tree.
To run a planar MoM analysis of your project structure, open the Run Simulation Dialog by clicking the '''Run''' [[File:run_icon.png]] button on the '''Simulate Toolbar''' or select '''Menu > Simulate > Run''' or use the keyboard shortcut {{key|Ctrl+R}}. The '''Single-Frequency Analysis''' option of the '''Simulation Mode''' dropdown list is selected by default. Once you click the {{key|Run}} button, the simulation starts. A new window called the "Output Window" opens up that reports the different stages of simulation and the percentage of the tasks completed at any time. After the simulation is successfully completed, a message pops up and reports the end of simulation. In certain cases like calculating scattering [[parameters]] of a circuit or reflection / transmission characteristics of a periodic surface, some results are also reported in the output window.
