I ran your code and added material properties. When I ran it just as you have with no section given to the small line, the mode shapes of the left long line act completely independent of the mode shapes of the right long line. The first pic i attached shows that.
Then I gave the same...
Thanks for the responses. I am introducing more key points into my beam because I want to give that small intermediate line different section properties than the rest of the beam. I.E., I want to have damage in my beam, but I want the beam to act as a whole.
For instance for the undamaged...
ANSYS Help: Simple Modal Analysis of Plate
I am modeling a plate (36"x3"x.25") in ANSYS. When I construct a line out of two keypoints and give the line a rectangular section, the analysis works and I can output modal displacements just fine. With these modal displacements I can plot the mode...
