&lt;p&gt;&lt;span style="font-family:verdana, geneva;"&gt;I am enclosing the details . I think there are some mistakes in my models. But I am not able to figure it out. Would any one be kind enough to check the models&lt;a href="https://communities.bentley.com/cfs-file/__key/communityserver-discussions-components-files/5932/7140.Fundamental-Time-Period-Trans-Direction.std"&gt;communities.bentley.com/.../7140.Fundamental-Time-Period-Trans-Direction.std&lt;/a&gt;&lt;a href="https://communities.bentley.com/cfs-file/__key/communityserver-discussions-components-files/5932/4760.Fundamental-Time-Period-Long-Direction.std"&gt;communities.bentley.com/.../4760.Fundamental-Time-Period-Long-Direction.std&lt;/a&gt;?&lt;br /&gt;&lt;/span&gt;&lt;/p&gt;
