I am trying out a random vibration study in a beam. It is a beam fixed on both ends and a remote mass is defined on mounted hole on the beam.
Input is the PSD curve base excitation. I would like to find the reaction force on those highlighted points bu the value is zero.
Also on the remote mass mounted hole the reaction value is zero for all the natural frequency values?

Reaction forces are calculated only on those geometrical entities which are used while defining a fixture.
For example in case of a cantilever beam, one can calculate the reaction forces only on the fixed end of the beam.
If you like to see the response at these particular nodes then you can make use of the Workflow Sensitive sensors and you can plot the graph by using Probe.
Try to split the beam up in parts and then hide the adjacent bodies. In that way you can access free nodes only on the part of interest and then use free body forces on the nodes of interest.
