New option in Eigenfrequencies calculation

In version 18 Try to reach 90% of horizontal effective mass option is added to Eigenfrequencies calculation. One has to set the starting number of shapes, then the program will calculate them and will check if 90% rule is passed. If it’s not, the program will calculate more shapes and checks the rule again in another iteration. There are two possible ways to end the calculation:

  • The 90% total effective mass is reached in horizontal direction
  • The maximum iteration number is reached

Remove connections from free edges

If an edge connection is defined at a shell edge that is not connected to any other structure, inaccurate results may occurre due to numerical problems. To avoid these problems, a new option to remove edge connections from free edges is available in Settings/All/Calculation/Analysis…. dialog.

If this option is checked, connections are automatically removed from the free edges before calculation.
