Modeling , Solar optics. It is significantly simpler to use these check boxes to accomplish that compared with changing the individual values in the windows previously described. The sequential calculation procedure within SolTrace does not allow a ray that leaves a stage to re-enter that stage again. Selecting an element by clicking in any cell in the row, then clicking the Z-Rotation button above brings up a window showing Euler angles and relationships with the aim point vector and the various axes. However, the user can manually enter a non-zero value for Cy 2 in the worksheet portion of the inputs. User defined optical property pages and stages will appear as sub items in the navigation tree once a file is loaded or edited. It is important that the user ensure that the surface used includes single axis curvature only otherwise unpredictable results may occur.

Copied data can be pasted directly into an Excel spreadsheet for example.

After translation of the child coordinate system origin from the parent coordinate system, these three rotations completely specify the orientation of the child coordinate system within the parent. Mathematically it makes no difference when they are applied, but functionally it is more efficient to do so in this way in order to eliminate needless ray generation and increased execution time.

For spherical surfaces there is clearly a maximum aperture defined by the diameter of the sphere. Simply click the appropriate toolbar buttons to view graphs or export the data to CSV files or the clipboard. Values of ‘0’ are dummy variables not used within SolTrace but must be included in the file. Trace Through for that stage was turned off, then that ray number will no longer show up in any of the following stage data lists as it is considered a lost ray.

Optical Properties Optical properties are defined on the second input page, shown below in Fig.

Stages can be added by right clicking on the System Stages icon; these stages are added at the end of the list. The solrrace continues to generate rays until the number of requested rays have fallen on elements of Stage 1. The first is displaying them all as one series or color.

Optical geometry definition input page showing the primary mirror stage for the High Flux Solar Furnace geometry. Every stage must have these parameters defined within the global coordinate system. In the Stage box will be a list of the stages within the system. The program will not allow a surface or contour plot if 1 more than one element is selected, or 2 the element surface is not flat solteace cylindrical.

There are two options for exporting the data in the Export Data section of this window. When using Global Coordinates with a point source, the distance to the elements is important so, for example, setting a point source at infinity requires a very large distance be specified. As shall be described later, the direction of the sun is defined relative to the global coordinate system.

It is expected that this script will work correctly in most cases, but may not fully import all stage properties Virtual, trace through, multi-hit etc The user must carefully design the optical system recognizing this sequential process. The File options allow the user to start a new project, open existing ones, open sample files provided at installation, save projects and set and open a working folder to aid in project organization.

The surface plot can be rotated and zoomed as in Intersection. This option also shows previously opened projects that can be opened directly with a left click. There are three options available to the user for displaying the ray intersections in “Coloring”.

Can be used with all apertures except Single r: The first two are commonly used probabilistic distributions.

In the “Interaction” column, the user can select between Refraction and Reflection.

The relevant parameter is the reflectivity and the element still possesses both back and front side values. As an aid to the user, a number of sun shape files have been included in the installation package along with the example geometries. This works in a very different manner than the cut and paste operations described below under Element Definition.

Other values can be entered and will result in the same set of random numbers generated for each new trace started. In fact, for many high concentration systems the choice of a pillbox sun is more than adequate. One option is to define a point in the global coordinate system such that a vector from this point to the global coordinate system origin defines the sun direction.

Before proceeding to the details of element definition, the three sections above the element data are described below. The code tallies the total number of rays generated within the rectangle, both those that fell on an element and those that did not, divides this number into the area of the rectangle and multiplies the result by the Direct Normal Insolation value described in the Visualization section.

If more than one element is selected both the power and centroid values are calculated for all elements. Each stage is displayed as a tab, much like worksheets in a spreadsheet.
