    change the status of a selectionblock from Required/Optional/Satisfied or enable/disable

    I tried using selection0.StepStatusAsString("Satisfied") but it doesn't work I also tried: selection0.Enable(False) but it keeps giving me error Many thanks

    NX journal - Selection filter rule in VB for "Product definition"

    Hi all, How can I filter for "Product Definition" using triplemask and UFconstants in a journal file? There's no way I can select the Surface finish object. Many thanks

    [NX 9] UG journal to select everything on screen

    Hi I´m having some problems with this task: I´m in the drafting environment, what I wanna do is select everything that is on my screen (dwg sheet) and move it to a certain layer (200), then I want to select all these object on layer 200 and copy/paste them onto another sheet (i.e. sheet 3). how...

    NX Advanced Simulation and Surface contact mesh

    Thanks Blas for the quick reply, unfortunately I have to use cgap elements because I also need non-linear elasto-plastic material and I don't have sol 601 license. In the other discussion you wrote: Also, revising the mesh I note that RBE3 RIGID elements are included in the FEM model!. In fact...

    NX Advanced Simulation and Surface contact mesh

    Hi all, I created a model with tet10 element, this model has 2 bodies in contact through 2 surfaces. I created a mesh mating condition Free-coincident between the two bodies so that the mesh were coincident. When I try to create the cgap elements between the two surfaces with coincident mesh...

    dynamic contact analysis with friction

    Hi, first of all i want to excuse me for my bad english. I need to make some analyses in patran and nastran with contact and friction. To do so i wanted to start with a dynamic analysis in order to understand better the parameters and their meaning. This analysis consists in making a cylinder...

    Sol 601/701 and 600/700

    Does anyone know if the bdf for a sol 600/700 is compatible with the sol 601/701 of nx nastran? Unfortunately I don't have Femap but only Patran and I wanted to know if the bdf of a sol 600 or 700 analyses could run into nx nastran by changing the number of the solution in 601 or 701. I...

    Contact problem

    ok so it was the BCs, I thought that limiting the theta displacement in the cylindrical system leaving only the radial displacement was enough. In my view it should have forced the axysimmetry of the structure. Thanks a lot for your help, you've been very helpful

    Contact problem

    So the problem was the BCs? beacuse when I ran the sol 101 analysis without the contact nastran solved it chttp://www.eng-tips.com/viewthread.cfm?qid=336068orrectly (the two rings of course where overlapping but the structure didn't have mechanisms). I know that what you did was correct and...

    Contact problem

    Hi I'm trying to do a very simple thermoelastic analysis, there are two concentric rings of different material to whom I impose a costant nodal temperature. I put the two rings in contact but it doesn't seem to work perfectly. It looks like the contact is respected only on one half of the two...

    Sol 129 contact simulation

    How do you simulate contact in SOL 129? does it support the bcontact and bsurf or do i have to use gap?

    RESTART SOL 106

    Hi I'm trying to restart a job because it has failed and I don't want it to run from the start because it's pretty long. the original bdf file was this one: SOL 106 CEND SEALL = ALL SUPER = ALL TITLE = Axial_Link_Bracket_Compression ECHO = NONE MPC = 200 SPC = 51...

    Contact analysis with TET10

    Steven thanks for your help. But is this valid only for the sol 600? if I wanted to run a 101 or 103 how should I do it?

    SOL600 Results

    fran11HD thanks for answering. So if I've understood correctly: - the 'time' it shows is simply the percentage of the load, it doesn't have anything to do with the actual time (seconds) (to me this is an incorrect way to show it). - there is no way to have only the last 'time step' in the result...

    SOL600 Results

    Hi I've made a Sol 600 analysis just to check if I could run it with no problem. It's a cantilever beam with linear material and BC but geometric nonlinearity. The problem comes when I import the results in Patran. The displacements values are exactly the same between the XDB file created by...

    Mesh on Mesh?

    I want to add that i don't have any geometry of the existing mesh, just the mesh

    Mesh on Mesh?

    Hi i need to mesh a surface but part of this surface is already meshed beacause it's the mesh of another surface and i want them to be congruent. Is there any way to tell patran to create a shell mesh on the new surface around the existing shell mesh? Thanks a lot

    Contact analysis with TET10

    Hi i'm trying to run a 101 contact analysis between two solids meshed with TET10. When Patran writes the bdf file it write this card: BCPARA 0 NBODIES 2 MAXENT 21470 MAXNOD 42940 and NASTRAN gives me this error: *** USER FATAL MESSAGE 5 (CNX_BOUDRY) Quadratic elements in...

    Patran and surface to surface contact.

    watching the video seems like i can do S2S contact even with sol 101, can i do the same thing with sol 106? without using CGAP i mean...
