Hi,<\/p>\n
I am simulating lamb waves in CFRP plates\/structures. For a 500x500x2mm plate I wanted to do a series of measurement at points placed every 0.5mm in a line. The motivation is doing a 2D FFT from (x, t) -> (k, f) to see which modes are present and if it fits with analytical & experimental results. I am running into a problem though:<\/p>\n
I only want to store the timeseries for the required points. I therefore add all the points to a named selection so that I can see which nodes they correspond to. They happened to be 436 points, corresponding to nodes 1587 to 2022, see below:<\/p>\n

<\/p>\n
I extract the data from the “.rst” file using the “ansys.dpf” Python3 module. The code is as follows:<\/p>\n
from ansys.dpf import post<\/span>
from matplotlib import pyplot as plt<\/span>
simulation_file = rf'C:\\Users\\rmehlig\\Desktop\\HPC_simulations\\Simulation_files\\{sim_identifier}_pwd\\{sim_identifier}.rst'<\/span>
simulation = post.load_simulation(simulation_file, simulation_type='transient mechanical')<\/span>
P0 = simulation.displacement(all_sets=True, components=[\"Z\"], named_selections=[\"P0\"])<\/span>
P1 = simulation.displacement(all_sets=True, components=[\"Z\"], named_selections=[\"P1\"])<\/span>
...<\/span>
plt.plot(P0)<\/span>
