Hi all!<\/p>\n

I’m trying an harmonic analysis with displacements boundary conditions (BC) coming from a table.<\/p>\n\n\n\n\n\n\n\n\n\n
\n

Frequency Hz<\/span><\/p>\n<\/td>\n

\n

Amplitude mm<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

0<\/span><\/p>\n<\/td>\n

\n

0<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

5<\/span><\/p>\n<\/td>\n

\n

0<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

5<\/span><\/p>\n<\/td>\n

\n

10<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

20<\/span><\/p>\n<\/td>\n

\n

10<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

20<\/span><\/p>\n<\/td>\n

\n

20<\/span><\/p>\n<\/td>\n<\/tr>\n

\n

30<\/span><\/p>\n<\/td>\n

\n

20<\/span><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

In the first colum of the table there is the frequency while in the second the amplitude to a given frequency. BC are applied to few nodes of the structure using the following command:<\/p>\n

Solution -> Define Load -> Apply -> Structural -> Displacement -> On Node -> Existing Table<\/p>\n

I cannot understand how to effectively perform the analysis because the solver seems to ignore the input value on the table in terms of amplitude at a given frequency. Basically the solver performs an harmonic analysis with a flat input.<\/p>\n

I really appreciate your support.<\/p>\n
