Detailed results for harmonic analysis

Since SCIA Engineer v 25, there is a results command that provides detailed results for harmonic analysis. This command is called Dynamics detailed. It is accessible via "Results → Dynamics → Dynamics detailed", or by default also from the "Process toolbar" in the "Results section".

Detailed results for harmonic analysis are available if at least one harmonic load case has been calculated in the project. To display the results, set "Type of load" to "Load cases" and then, in "Load case", select the harmonic load case for which you want to display the results.

Dynamics detailed - harmonic analysis load case

For harmonic analysis load case results, the "type of values" might be selected as "displacement", "velocities" and "accelerations". For each type of value, the corresponding values of translational and rotational motion might be selected, as well as the total value (the vector sum) and more components (multiple values to be displayed at once).

The "Evaluation for" property might be set to:

"Peak values" - the maximal values from the harmonic response of the structure (sinusoid) are displayed

"RMS values" - where "RMS" stands for "root mean square" - as the harmonic response is considered to be sinusoidal, the root mean square is practically multiplying the maximal peak value by the constant value of 0.707107 (what is √2 / 2).

The check box property "Result in all FEM nodes" offers to plot the result in all the nodes of the finite element mesh. If the mesh is fine, this might be graphically in 3D scene rather unreadable. However, the export into excel sheet from the "result table" might have some practical application in order to see the results in all the mesh nodes.

Units

In order to change the units of accelerations or velocities: "Unit system" → "Manage units" → "Dynamics" → and the corresponding entities - see the figure below:
