    NX Nastran

    Hi everybody, I am managing a SOL 601,106 with Nx Nastran (NX8). Does anybody know why even if I have required to plot the STRAIN ENERGY in the case control, nothing appear when I load the results? Thanks in advance

    Nonlinear buckling

    Hi, I am trying to identify a structural instability with nonlinear solution (106) in a very simple model, a beam loaded by a force acting with a 2° angle of incidence (to generate the lateral instabililty). What happens is as follow: - setting "ITER, 1" as "KMETHOD, KSTEP", the simulation, as...

    Follower Forces in NX NASTRAN

    Hello to everybody, is anyone able to tell me how can I set a force to be follower (i.e. mantain its direction against the grid point to which is applied) in NX-NASTRAN environment... Thanks in advance!

    Follower Forces in NX8

    Hello to everybody, is anyone able to tell me how can I set the force to be follower (i.e. mantain its direction against the grid point to which is applied) in the ADVANCED SIMULATION environment of NX8? (or at least in NX-NASTRAN environment...) Thanks in advance!

    CBUSH-1D

    Hello everybody, does anyone knows how to model a CBUSH-1D in Femap (10.3.1)? I find easily the card for the CBUSH property, but nowhere information about the mono-dimensional one. Thanks in advance!

    Cbush preload

    Dear all, does anyone has an answer to this two problems related to bush preload? 1 - in a 106 simulation, I modeled a nonlinear spring with a cbush with nonlinear F_VS_Displ dependency. Now I am looking to set a preload to this element, and I tried to set the curve to have a non-zero initial...

    Non linear spring in NX Nastran 8.0

    Hello Everybody, Does anyone can tell me how can be a non-linear (Force vs displ.) modeled in Nx Nastran 8.0? I need to include non linear spring in a 106 (or 601) simulation, and I know that Nastran allow to do that using the PBUSHT card. Unfortunately I didn't find any reference about that...
