  Good morning,
  I'm studying the transient behaviour of a structure with U-flipped shape. As input I excite the structure with a sine signal produced with matlab and I applied it to the two nodes at the base: the file is a table with two columns (one for the time and the other for the displacement) and a number of rows depending on the sampling frequency. To import the file I use *DIM and *TREAD. Even though it's seems correct to me, the displacement field is applied to only one node of the two selected. What can the error be?

  Hi,
  Can you please share the command you have used to select the nodes and apply the displacement?
