Workbench allows you to create a Nodal Named Selection. Then you can use the Named Selection to define loads.nYou can define a Force on a Vertex.nHere is the ANSYS Help description for Force loadingnYou can have frequency dependent force. I have never used this. I assume that it will linearly interpolate the force for all the frequencies between the values in the table, but I don't know that for sure. I would make sure the Frequency upper and lower limit in Analysis Settings matches the largest and smallest values in the load table.n
