 [Felt-users] Modal analysis problem From: - 2004-02-21 15:47:35 ```Dear Sir, I am trying to do a simple modal analysis with WinFElt when I ask it to solve the problem it starts to work and never ends. Could you help me to figure out what is going wrong? The problem that I'm trying to solve is a simple frame built with beam3d elements (two vertical beams and a horizontal beam connecting the two vertical beals, and the two vertical beams have one end fixed), you can see the listing at the end of mail. Thank you very much, Cristiano problem description title="portique" analysis=modal nodes=4 elements=3 analysis parameters mass-mode = lumped nodes 1 x=0 y=0 z=0 constraint = fixed 2 x=0 y=1 z=0 3 x=1 y=1 z=1 4 x=1 y=0 z=1 constraint = fixed beam3d elements 1 nodes=[1 2] material = steel 2 nodes=[2 3] material = steel 3 nodes=[3 4] material = steel material properties steel A=3.1416e-4 E=211e9 G=8.1154e10 Iz=7.854e-9 Iy=7.854e-9 J=15.708e-9 rho=7800 constraints fixed Tx=c Ty=c Tz=c Rx=c Ry=c Rz=c end ______________________________________________________________________ Yahoo!
