Strange eigenmoden for a split geometry.

noravivian.yazdandoostkhosravi over 5 years ago

Hey,

I have created a splitted plate with the same material. The mesh seeds are on the exterior.

The result from the modal analysis shows a deformation only at one side (shown in the picture).

Why does only half of the geometry react at this eigenfrequenz?

Have you "equivalenced" the model? If you only plot the elements (erase the geometry, or make a group of just Fem that is the only group posted) and then set the element display to free edges (or verify mesh boundary) does it show a line (crack) between the two sides?
