why is it important to recognize the symmetrical nature of design in performing FEA analysis?

Solution

It is important to recognize the symmetrical nature of design in performing FEA analysis as it allows only a portion of the structure to be analyzed with a consuquent saving in data preparation and computer processing time. Recognition of symmetry conditions can be done by either visualization of the displacement field, or by imagining certain rotational and or reflection motions.
