I have been using the ANSYS Additive Print & Science simulation framework to model residual stress after a LPBF print (thermal strain simulation), and used the thermal history simulation to view average temperature around the melt pool during each layer of the print.

My question is: Is it possible to extract the transient temperature data throughout the build process (i.e. for a given node, view the temperatures over time for the whole build)? Based on the description of how the thermal solver works, it seems as though this data should be computed but I cannot see any way to export this data on either the thermal strain simulation or the thermal history simulation.

It appears as though this question was asked previously but not resolved:

Thank you.

In WB-Additive, it is possible to extract the transient temperature results at a specific nodal location. You need to first enable the export of nodal data in Mechanical GUI by going to File => Options => Export and setting "Include Node Location" to "Yes".  Additionally, after running the simulation, create a named selection and scope result to the strategic node of interest.  Then, with this Named Selection result highlighted in the Solution Branch, click on the top left corner of the Tabular Data (next to the graph), RMB and click on 'Select All' and then click on  'Export'.    You can choose to send this result set to either an excel or txt file.

Thanks for the response! I was able to use this method to extract the data in WB-Additive. Is is possible to extract similar data in the ANSYS Additive Print and Science software (I am currently using Additive Manufacturing 2023 R1)?

Thank you for your assistance, it is greatly appreciated.
