Hello everybody!

How is it that when I define damping in FRF analysis I obtain zero displacements? It is not true because when doing the Time history analysis I have non-zero displacements. The displacement are very small but still are (like 10 micrometers). It may be because of the scale (I receive displacements in [mm] ), but it is impossible to  change the scale of the graph. When analising the table, the displacement are also equal to zero. Can anybody tell me what might be the problem?

So how can I send it to you? My file has 40MB
