The spreadsheet should now looks like this:. The instructions added so far all used the default simulation period whole simulation and the default line position arc length 0. However, this is laborious and error prone if a lot of results need transferring, so we have developed special facilities to automate the process. You will see the instruction being added to the worksheet but the instructions wizard will remain open allowing you to add yet more instructions. A file name field and a browse button will now appear. This time, to add the instruction click the “accept and go to next” button.

Or you can, of course, choose to enter the label text yourself. A file name field and a browse button will now appear.
So the next step is to select the first instruction row by clicking on a cell in row 5. Orcaflrx instructions wizard creates and inserts instructions on the currently selected row.
There are situations where these column headers are undesirable and if that is so the “exclude header text” box can be checked to suppress their output. If not checked then the values in the sheet will remain unchanged.
You can choose to use a default label, in which case the text lrcaflex the label will be constructed from the current instruction. Suppose that you want time histories of X, Y and Z for the line.
Now create an OrcaFlex spreadsheet and save it in the same directory as the simulation file. Notice how slightly different options are available reflecting the fact that range graphs are orfaflex in a slightly different way from time histories.
More than one instruction can be added at once. You should see four time histories output on a new worksheet named “Results”. Open the instructions wizard again and select the Time history command.

This time, to add the instruction click the “accept and go to next” button. The one part of the instructions wizard which we have not yet discussed is the section titled “labels” as shown below:. There are even commands for reporting model data: Try selecting different simulation periods and adding further instructions.
Post-processing: Instructions wizard
Using relative paths makes it easier to rename the directory or move the spreadsheet and OrcaFlex files to some other directory. It is usually most convenient to save it to the directory containing the OrcaFlex files from which you want to extract results. Line results require you to specify the point on the line for which you want the results, e.
Click the browse button and select the simulation file you saved in the first part of this tutorial. In the object list select an OrcaFlex line object if you are using the A01 Catenary Riser example, select the Catenary Hose and then select effective tension from the list of variables. OrcaFlex users often use spreadsheets to post-process their OrcaFlex results.
This shortcut creates a new spreadsheet based on the template.
Then open the instruction wizard by clicking on instructions wizard on the OrcaFlex tab of the Excel ribbon. You can then use the normal spreadsheet facilities to calculate other post-processed results from those OrcaFlex results.
