There is a lack of explicit documentation on extracting specific motion results from Simcenter 3D Motion.
Solution
First download and install the Simcenter 3D Motion Results Reader from the GTAC Download site. This will be found under the Add-Ons folder for each specific release (2019.1, 2019.2, etc) and should work across all versions of each respective release.
Next, open your Simcenter 3D Motion simulation file. Solve the model in order to generate the .mres results file. Open Simcenter Results Viewer from the Results tab. Create a scenario from the newly created .mres file so that you can view the element and short-hand variable names associated with each element. You will use this data set to determine the output that you want to export from your Simcenter 3D Motion model.
The next step is to create a list of output channels in a text file to specify the data that you want to export from the Motion simulation. It will follow the format of ElementName:ShortVariableName. You can find a list of these from the opened Results Viewer session where the short-hand names are shown in the [brackets]. Once you are aware of the different available variables, it won't be necessary to open Results Viewer and view the variables. Save the list of output channels in the same directory as your model as results file.
Once you have specified the output channels, create a batch file in the same directory as your results file. Set up the file in a similar way to the example below with following variables to the corresponding values:
Once this is complete, save and close the file. You can now double click on the batch file and the results will be pulled from the .mres file and organized in a new text file for the exported results.
