=== Viewing & Modifying You can view and examine the discretized version of your scene objects as they are sent to the SBR simulation engine. You can adjust the mesh resolution and increase the geometric fidelity of discretization by creating more and finer triangular facets. On the other hand, you may want to reduce the mesh complexity and send to the SBR engine only a few coarse facets to model your buildings. Unlike [[EM.Cube]]'s other computational modules that express the default mesh density based on the wavelength, the resolution of the SBR mesh generator is controlled by the '''Mesh ===Cell Size''' parameter, which is expressed in project length units. The default mesh cell size of 100 units might be too large for non-flat objects. You may have to set a smaller mesh cell size in EM.Terrano's Mesh Settings dialog, along with a lower curvature angle tolerance value to capture the curvature of your curved structures adequately.
You can view and examine the discretized version of your scene objects as they are sent to the SBR simulation engine. To view the mesh, click the '''Mesh''' [[FileImage:mesh_toolInfo_icon.png|40px]] button of the Simulate Toolbar or select '''Simulate > Discretization > Show Mesh''', or use the keyboard shortcut {{key|Ctrl+M}}. A triangular surface mesh of your physical structure appears in the project workspace. In this case, EM.Terrano enters it mesh view mode. You can perform view operations like rotate view, pan, zoom, etc. But you cannot select objects, or move them or edit their properties. To get out of the Mesh View and return Click here to EM.Terrano's Normal View, press the {{key|Esc}} key of the keyboard, or click the Mesh button of the Simulate Toolbar once again. You can adjust the mesh resolution and increase the geometric fidelity of discretization by creating learn more and finer triangular facets. On the other hand, you may want to reduce the mesh complexity and send to the SBR engine only a few coarse facets to model your buildings. To adjust the mesh resolution, open the Mesh Settings Dialog by clicking the '''Mesh Settingsabout ''' [[File:mesh_settingsMesh_Generation_Schemes_in_EM.png]] button of the Simulate Toolbar or select '''Simulate > Discretization >''' '''Cube#Working_with_Mesh_Generator | Working with Mesh Settings...'''. This dialog provides a single [[parametersGenerator ]]: '''Edge Mesh Cell Size''', which has a default value of 100 project units. If you are already in the Mesh View Mode and open the Mesh Settings Dialog, you can see the effect of changing the mesh cell size using the {{key|Apply}} button.  Some additional mesh [[parameters]] can be accessed by clicking the {{key|Tessellation Options}} button of the dialog. In the Tessellation Options dialog, you can change the '''Curvature Angle Tolerance''' expressed in degrees, which has a default value of 45°. This parameter can affect the shape of the mesh especially in the case of solid CAD objects with curved surfaces. Note that unlike [[EM.Cube]]'s other computational modules that express the default mesh density based on the wavelength, the resolution of the SBR mesh generator is expressed in project length units. The default mesh cell size of 100 units might be too large for non-flat objects. You may have to use a smaller mesh cell size along with a lower curvature angle tolerance value to capture the curvature of your curved structures adequately.
