<\/p>\nHello,<\/p>\n
I’ve generated transient solution data with Workbench, coupling ANSYS Mechanical to Fluent. I have a 2.5D domain with a membrane fluttering in a fluid stream. The membrane is clamped at its leading edge and undergoes self-excited oscillations. This screenshot shows the FEM geometry with the undeformed mesh. The upper horizontal face of the membrane is highlighted in green. The FSI interface includes the upper and lower horizontal faces, as well as the semicylindrical face of the trailing edge.<\/p>\n
<\/p>\n
I want to export a number of quantities from the upper and lower surfaces to process the result data outside of Mechanical (e.g., MATLAB), as a function of time:<\/p>\n
Eventually, I want to merge the data from the upper and lower surfaces into a 1D-description of the membrane, to express displacement, velocity, acceleration, and pressure difference as a function of a Lagrangian coordinate, “s”, along the membrane. To achieve this, I’d like to get a file for each time step of the solution, each file containing a list of nodes (or faces, or coordinates along the face) and the associated quantities, one column per quantity.<\/p>\n
With the GUI of Mechanical I don’t find a way to export the nodal data of a face, even not at a single instant of time. Please provide guidance on how I should approach this task, and where to find resources that explain what I need to know. Maybe I need to write a Python script, or an APDL script? If so, where to learn how to do that?<\/p>\n
<\/p>\n
Thank you in advance for any constructive replies.<\/p>\n","protected":false},"template":"","class_list":["post-308166","topic","type-topic","status-closed","hentry","topic-tag-2-way-coupled-fsi","topic-tag-ANSYSTransient-1","topic-tag-automation","topic-tag-export-deformed-geometry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
