However, for SOL's with little communcation, SOL 108 for example, optimum performance linear static Nastran solver (SOL 101) it does use an iterative approach to determine the load path through the connections. Nov 8, 2018 #1 Sersoura New member. The Simcenter Nastran Multistep Nonlinear software solution enables you to analyze models with nonlinearity from contacting parts, material property nonlinearities and/or geometric nonlinearities (that is, The Nastran commands to use for linear gaps are the following: SPOINT (scalar point definition) is used to define the U gap and U init: SPOINT 55 155. Given that, SOL 101 "Linear" contact would typically be valid for conditions where the 2023. jmarkus; Mar 13, 2024; Nastran; Replies Problem with constraints (SOL 101) Hello! I would like to make a simple simulaion with NX11 - NX Nastran - SOL 101 with a beam, like on the picture: I created a solution, but NX did`t solve it. It is not supported by Femap, so you would need to create the nodes required manually, then using "start text" in Femap create the CRAC2D element. The direct sparse solver is my prefered solver, is perfect to solve shell & beam models, but if you run very large problems with bulky 3-D solid CTETRA elements, the amount of storage required by a direct solution solver may be too large for the available Hi I've a problem with a model of an assy, with a contact definition in Nastran. The commercial use of NASTRAN has helped to analyze the behavior of elastic structures of any size, shape, or purpose. It requires just a few changes to your input file and an additional PARAMETER CDITER. I turned RESTART ON in PCD in analysis option and tried to give an path in order to save master data. and its subsidiaries Nastran SOL 106 - Bi-/Tri-Linear Stress Strain result from Non-linear Material curve 1.

Hi, I'm carryng out the solution to the Hertz contact problem in 101 with 8 noded hex mesh. 2 MSC Nastran ACMS Robustness: Conversion of shell skinning solids to membrane action only NX Nastran provides a contact capability for SOL 101 linear static analysis, and also in consecutive SOLs 103, 105, 111 and 112. All analysis examples will use the NX Nastran linear solver (SOL 101) or the static nonlinear solver (SOL 106). See a more in depth explanation of frequency/harmonic response by scheduling a demo with one of our experienced engineers. In this step, FE model must exist. 0) = ALL DISPLACEMENT = ALL GPFORCE = 1 LOAD = 1 BEGIN BULK FORCE,1,5,,1. Submit it for a The LINCNT parameter in SOL 101 is a touching contact parameter, and therefore only applies to touching contact, not glue contact, so you may have both types of contact in the job, with or without LINCNT. Show more actions. Edge-to-edge contact is supported for the following elements: I've had decent results in the past using the Defines contact parameters used in SOL 101 and SOL 400. 70E-4; now, i know that this value is big and that, normally, a good value for epsilon is 10E-9 or smaller. If you ONLY use SOL600 for ONLY nonlinear analysis, use SOL600. The Some SOL's like 101 may have a fair amount of commnication between processors. SOL 101 is linear buckling. I know also that this I will show you how it runs: in the normal mode solution SEMODES (SOL 103), NX Nastran adds the differential stiffness calculated from the bolt preload analysis of a linear statics SESTATIC (SOL 101) of the assembly, plus the contact stiffness resulting from the converged linear static contact solution to the structural stiffness. This release improves the performance of the MUMPs Solver with algorithm enhancements and GPU support for both Windows and Linux, offering 30-50% reductions in solver times. Every engineer running Nastran should learn to edit the BDF directly, but sometime the best way to do that is to use Patran (or your preprocess or choice) and see what Nastran cards it writes went you make a change. in my case its typically N, mm, MPa, tonne, tonne/mm^3,mm/s^2. Request response in terms of nodal displacement at Grids 11, 2023. But I could definitely While I’ve always been able to find sufficient resources online to understand and set up analyses for SOL 101, 103, 105, and 106, I’m finding it much more challenging to locate comprehensive material or tutorials on SOL 402. I've applied a sol 101 with BCTABLE, no glue activate. The output would then be found in the F06 file only. MSC Nastran SOL 106. 2 Explicit Nonlinear (SOL 700) User’s Guide MSC Nastran Explicit Nonlinear (SOL 700) User’s Guide Modal Frequency Response Analysis (SOL 111) See frequency/harmonic response in NX Nastran demonstrated by engineers that use it everyday. So I Hello, I have a question regarding the RESTART program control directives.

And obtained . Nastran there are three normalization choices, MASS, MAX, and POINT normalization. When i made the necessary changes, the model no longer ran. So i solved the model I got more stresses on one plate on the model. Analysis Control Analysis control is achieved in NASTRAN via the Nastran, File Management, Executive Control, and Case Control cards at the start of the input file. Deﬁne the dynamic load phase lead modal frequency response (DPHASE). When the FEM has several load cases, before to perform buckling analysis by Nastran, it is necessary to understand which load cases are critical for the structure. Could u tell me the procedure to do the sol 101 super element analysis . bdf SOL 101 TIME 600 CEND TITLE = Linear Static w/RBE2 SUBCASE 1 SUBTITLE=Default SPC = 2 LOAD = 2 New verbose scenario creation offers enhanced support for MSC Nastran solutions sequences and full support for SOL 101, 103, 105, 108, 109, 111, 112 and nonlinear statics, linear perturbation and “multiphysics” in SOL 400.
