The examples are intended to be performed in order, as the each builds on the skills and familiarity of the previous. Syntax note: When referring to a menu item, the convention is “Main Menu Item”|”Sub Menu Item”. For example, the menu item found under the “File” main menu called “Save” is referred to as File|Save. Example 1a: Create a basic Virtual Material Module simulation Requires Virtual Material Module Click the Create Simulation “Sprocket” icon in the toolbar or click Data|New Simulation. March 6, 2013 Page 2 RAVEN Examples The “Select Simulation Type” dialog pops up. Select “Virtual Material Simulation”. The Create new simulation dialog box pops up. March 6, 2013 Page 3 RAVEN Examples Select material as “TORAY 2510-P707AG-15 Tape”. Click the Default Cycle button, or click the drop-down button and select one of the listed cure cycles. The dialog should now look like: March 6, 2013 Page 4 RAVEN Examples Click the “OK” button. The run completes quickly and a summary report appears in the Report Window. March 6, 2013 Page 5 RAVEN Examples Note that this material reports which models have been characterized, as well as the limitations present in the model. Additionally some summary information (final degree of cure, final Tg, flow index) is presented. The Data Tree now shows the simulation under Master analysis group 1. The simulation name is the name given in the Create new simulation dialog, which, if it was left as “Auto” is simply the name of the material. Save the workspace using the Disk Icon or by choosing File|Save. For use in the remaining examples, save the file as “Example1a.rws”. March 6, 2013 Page 6 RAVEN Examples Example 1b: Create a plot from a basic Virtual Material Model simulation Requires Virtual Material Module Open the “Example1a.rws” file created in Example 1a. Click the Create Plot button, or select Plots|New Plot... March 6, 2013 Page 7 RAVEN Examples The New Plot: Create Series dialog pops up. Press the OK button to plot Temperature as a function of Time on the main axes. March 6, 2013 Page 8 RAVEN Examples Right-click on the plot and select New Series..., or select the Plots|New Series menu item. The Create Series dialog pops up, very similar to the dialog that pops up when creating a new plot. March 6, 2013 Page 9 RAVEN Examples Choose “Degree of Cure” from the Y-axis data drop-down and make sure that it is plotted on Y-axis 2. March 6, 2013 Page 10 RAVEN Examples The resulting plot is shown below: You can access a number of plot manipulation tools from the toolbar including: Pan, Zoom, and Probe The pan tool can be used to drag the plot around. The zoom tool allows you to draw a window around portions of the plot to zoom in The zoom can also be reset with the zoom extents button. The zoom can be increased or decreased stepwise using the increase/decrease zoom buttons. March 6, 2013 Page 11 RAVEN Examples The probe tool allows you to determine the value at a point beneath the probe. The value is reported in the report window. You can also probe for a slope , local maximum or local minimum These tools are also available by right-clicking the plot. Further, you can show/hide the gridlines, show/hide the legend, show/hide detailed series labels, and export the plot image and data in various ways. Various plot parameters can be adjusted by selecting the “Edit plot...” item (which is also available via right-clicking the plot, right-clicking the plot name in the plot tree or by selecting Plots|Edit Plot. March 6, 2013 Page 12 RAVEN Examples Axis properties can be changed by double-clicking or right-clicking on the axis. Save the workspace as Example1b.rws. March 6, 2013 Page 13 RAVEN Examples Example 1c: Modifying an existing simulation and using the cycle editor Requires Virtual Material Module Load the Example1b.rws workspace. Open the Edit simulation dialog by double clicking on the simulation name in the data tree or by selecting Data|Edit simulation... March 6, 2013 Page 14 RAVEN Examples In the Edit simulation dialog, you can change the simulation name, the material involved, or the cycle. Click the edit cycle button. March 6, 2013 Page 15 RAVEN Examples The Cure Cycle Editor dialog pops up: Change the initial ramp temperature target to 175 F and the initial ramp rate to 2.0 F/min by double clicking the numbers in the list, typing in the new numbers, then pressing the Enter key. In a similar manner, change the hold time to 60 minutes. With the 60 minute hold selected, click the “<<Ramp” button to add a second ramp to the cure cycle. Change its ramp target and rate to 270 F at 3.0 F/min. Add a 60 minute hold by clicking the “<<Hold” button. March 6, 2013 Page 16 RAVEN Examples Finally, change the cycle name to “Two Hold”. Note that you can also click and drag hold and ramp segments of the cure cycle in the cure cycle window. The temperatures and rates will snap to rounded-off values. If you need more precise values, input the numbers directly in the cycle segment list. Save the cycle as “Two-hold.rcf” by clicking the Save icon in the Cure Cycle Editor. Click OK to return to the Edit simulation dialog. The new cure cycle should appear in cycle pane on the right. March 6, 2013 Page 17 RAVEN Examples Click OK to update the simulation results. Save the workspace as Example1c.rws March 6, 2013 Page 18 RAVEN Examples Example 1d: Basic simulation the easy way Requires Advanced Thermal Profile Module The steps in Example 1a and 1b are rather manual. The Workflow Automation Tasks simplifies these steps by automating many of them for you. Create a new workspace by clicking the Create a New Workspace button. Click the “Basic simulation” link in the Tasks pane. The same “Create new simulation” dialog box as seen in Example 1a is displayed. Select material as “TORAY 2510-P707AG-15 Tape”. Click the Default Cycle button, or click the drop-down button and select one of the listed cure cycles. After setting the simulation parameters, the simulation runs, but a plot is automatically generated and populated. March 6, 2013 Page 19 RAVEN Examples March 6, 2013 Page 20 RAVEN Examples Example 2: Compare 1 material with two cycles Requires Advanced Thermal Profile Module In Example 1, we created a basic virtual material simulation of Toray 2510 using the average manufacturer's recommended cure cycle (MRCC). Then we modified the cure cycle. But, how did the results of the first simulation compare to that of the second? Select the “Compare two cycles” link form the Tasks pane. In this case, the Workflow Automation wizard appears, leading you through the steps required to perform the analysis. The first step is to select the material. Select Toray 2510. March 6, 2013 Page 21 RAVEN Examples Click the “Next >” button. March 6, 2013 Page 22 RAVEN Examples The next step is asking you to define the baseline cure cycle. Use the default cycle by clicking “Default Cycle”. March 6, 2013 Page 23 RAVEN Examples Click the “Next >” button again, and Step 3 is shown. This is also a cure cycle selection dialog box. In this case, click the “Open Cycle” button, and select the “Two-hold.rcf” file you created in Example 1c. The Cure Cycle Editor pops up, allowing you to make any changes you may want. Just click “OK” in this case. Click “Finish”. The two simulations are run and a plot is created, showing the temperature, Tg, DOC, and cure rate history of each. March 6, 2013 Page 24 RAVEN Examples The plot is a little cluttered. Turn off the legend by right-clicking on an empty area of the plot, and selecting “Hide Legend”. Individual series or groups of series can be turned on or off by checking or unchecking the appropriate checkboxes in the plot tree. Turn the Tg group off by unchecking it. March 6, 2013 Page 25 RAVEN Examples Notice that the cure rate of the two hold cycle spikes while the material is being heated.
