When creating a bushing element with CBUSH and defining the properties of the bushing with a PBUSHT card, which references TABLEG cards to define a load-deflection-curve, which of the columns has to be the load and which deflection? Or asking the other way round: in the example below, where the first value is the deflection, the second value is the force, do I have to use XY or YX?

$ CBUSH*              1401              27            1401            2401 *                                                                      3 $ PBUSHT*               27              KN               1               2 *                      3                                                 $ TABLEG*                1                          LINEAR              XY *                      0 *                  -0.35        -20000.0 * *                   -0.3         -8500.0 * *                   -0.2         -3500.0 * *                  -0.15         -2000.0 * *                   -0.1         -1200.0 * *                    0.0             0.0 * *                    0.1          1200.0 * *                   0.15          2000.0 * *                    0.2          3500.0 * *                    0.3          8500.0 * *                   0.35         20000.0 * $

    as far as i remeber you need to use TABLED1 to input displacement x force curve, in this order. First collumn disp and second, force.
