For extracting displacements from Modal analysis, please find below an example script, which prints ux, uy and uz for node 310 for Mode 6. This can be further expanded to loop over each mode and export displacements for all nodes.
import mech_dpf import Ans.DataProcessing as dpf #Extract Modal analysis system analysis = Model.Analyses[0] ds = dpf.DataSources(analysis.ResultFileName) #mesh scoping my_scoping = dpf.Scoping() my_scoping.Location="Nodal" my_scoping.Ids = [310] #Time list timelist = dpf.operators.metadata.time_freq_provider(data_sources=ds).outputs.gettime_freq_support().TimeFreqs.Data time_index_list = range(1,timelist.Count+1,1) disp_fc = dpf.operators.result.displacement(time_scoping=time_index_list, data_sources=ds, mesh_scoping = my_scoping).outputs.getfields_container() #Print ux, uy and uz for Mode 6 for Node 310 print(disp_fc[5].Data)
