The calculation of Eigenvalues is the first step in many dynamic calculations. Despite it involves advanced structural engineering concepts not always studied in deep in some civil engineering courses it is quite simple to do it in RM Bridge within OpenBridge Designer.
Since the Modal Analysis is generally a good indication of the model behavior it is also used just to check the structure. Therefore, as shown below, now the user has an option to automatically include it in the Structure Check when using the Recalculate Modeler and going from the Modeler to the Analyzer.
The Eigenmodes or Eigenshapes are then plotted and usually show if the current computational model is good enough or needs additional adjusting or refining.
