Eigen Value Analysis Problem

[alirezaarab]

Hi

I am modelling a 3D RC moment frame using ShellMITC4 as roof slab when using nodeEigenvector in order to obtain mode shapes I got following error "warning node Eigenvector nodetag? dof? - eigenvecor too large".
I do not need this mode shape because its mode participation factor is small but I am curious about this error. Can any body help me?

Thanks

the nodes store the eigenvectors after the eigen command as a matrix .. when you issue this command, the application goes and asks the node for this matrix .. if the number of columns in this matrix is less than the eigenvector specified this error will pop up .. try a "print node $nodeTag" before this command to see how many eigenvectors are stored at the node.
