Tables > Springs > Nodal Springs prompts you with the following dialog.
It allows you to enter nodal springs in a spreadsheet. Each nodal spring includes the node ID, the spring non-linearity flag and six spring coefficients Kx, Ky …, Koz. The node ID must be valid (defined).
The spring flag is a string of 6 characters representing the spring non-linearity in three translational DOFs (Dx, Dy, Dz) and three rotational DOFs (Dox, Doy, Doz). For each character in the flag, enter ‘0’ if the restrained DOF is linear, ‘1’ if compression-only and ‘2’ if tension only. For the unrestrained DOFs, just enter 0s for the corresponding spring coefficients.
An empty row is allowed if all rows below it are empty. Selected rows (whole row must be selected) may be cut by clicking the button “Cut Selected Rows”.
