  3. Hello everybody, I have some problems with stress initialization simulation of solid element: I'd like to do a simulation made of two step where the second step shall take into account strain and stress of first step. I have try to use \inista but there is something wrong because in second step, at first frame, the part have no stress. The procedure I have used is: - STEP I: /IOFLAG - eport solver deck from HyperView for the deformed shape - STEP II: /INISTA In attach the file .rad of simulation. Thank you in advance for your help!

    long time response

    Hello, collegues! my question is how to perform hm for large assemble working? i have a model which consists more than 4 mln elements and i am upset... every operation i'm waiting for a long time. why does HM work so long? i understand if HM saves my large file or checks all model. but i have masked large part of model and work with less than 10 details which consist average 1000 elements. i was remeshing/connecting each over. and i was waiting every operation 1 minute or 2 sometimes... my computer isn't weak. any idea? thanks a lot!
  5. Hello! I'd like to create a bullet as shown in the image attached. It has a core and a jacket around it. They're touching but have no penetrations. I drew the geo in SolidWorks and imported. But when I use the general approach of partitioning and solid mapping, in my analysis it will show penetrations between the jacket and core. How do I go about avoiding this?
  6. Hi , Need clarification regarding FRF analysis using Optistruct . What is the need of taking PHASE response in the tutorial - OS-T: 1300 Direct Frequency Response Analysis of a Flat Plate ?? Then what is the use of below responses ??/ Regards, Arul
  7. i want to do thermal conduction analysis of a rod. length = 100 mm , radius = 10 mm . temperature on one side is 250 degree & 150 on other side. k = 230 w/mk. how to apply temperature & boundary conditions to the body. i want to find out temperature variation.
  8. Here's a bit of a challenge and certainly one which has bamboozled me so far... Our models need to follow a particular numbering system, we already have a code which quickly renumbers literally everything in the model to a specific number range. But an add on we would like is to be able to rapidly renumber specific node numbers. In the models, we tag nodes with a label like "N-9001" meaning that node number must be 9001 (long story but we work on include files which must slot together so certain nodes must be certain numbers). At the moment this is a manual process but what I would like is a code which could createmark by tag name N9001, then renumber node to 9001. Can this be done? If so, how?

    HM Output Settings LS-Dyna

    Hi, I recently started to use Hypermesh 2017.2 as a Preprocessor for LS-Dyna. I'm already quite satisfied with the usability besides one exception: since we're using LSPrepost for the model creation as well, which is providing a clean and structured output regarding the keywords, Hypermesh doesn't: LSPrepost: *MAT_PIECEWISE_LINEAR_PLASTICITY_TITLE ALUMINUM PURE 99.45-O CONDITION $# mid ro e pr sigy etan fail tdel 12.71300E-6 68948 0.33 0.013362 0.0 0.2723 0.0 $# c p lcss lcsr vp lcf 0.0 0.0 3 0 0.0 0 $# eps1 eps2 eps3 eps4 eps5 eps6 eps7 eps8 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 $# es1 es2 es3 es4 es5 es6 es7 es8 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 HM: *MAT_PIECEWISE_LINEAR_PLASTICITY_TITLE ALUMINUM PURE 99.45-O CONDITION 12.7130E-06 68948.0 0.33 0.013362 0.0 0.2723 0.0 0.0 0.0 3 0 0.0 $$ HM Entries in Stress-Strain Curve = 8 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 I also attached the original and HM output file to point out the difference. As far as I see, I'm not using very fancy keywords that HM should be able to process and which it's doing for the *DATABASE and *CONTROL keywords. Are there any setting options I missed? Or do I need an add-on to receive clean keyword output throughout the whole file? Thanks in advance for your support.

  10. i have these doubts please explain anyone 1) To converting rigid bodies into flexible bodies in hypermesh opti, Why we are going for modal analysis? 2) is there any method other than Modal analysis?? please help me with this thank you
  11. Hi all, Am trying to find a line of code which will select a component / assembly / set etc, when the name contains a certain string... for instance the assembly name may read "apples-001001a" but I want a script to select that assembly if the name contains "apples" as the number could change in the future. Any ideas? Cheers Andy
  12. Hello everyone, I was wondering if there is a way to export a .txt file with the connectivity of all the elements on a model. For example: My model is made of CQUAD4 elements only. The ideal output would be a list like this: ELEMENT_ID,CONNECTION_1,CONNECTION_2,CONNECTION_3,CONNECTION_4 With CONNECTION_X being: CONNECTION_1 - Element connected to G1-G2 CONNECTION_2 - Element connected to G2-G3 CONNECTION_3 - Element connected to G3-G4 CONNECTION_4 - Element connected to G4-G1 If there was no element connected, CONNECTION_X would be 0 (for example) I've tried to assemble this connectivity matrix based on the bulk data exported by Hypermesh using MATLAB(it's the only language I'm comfortable with) using the CQUAD entry to go element by element and then search the whole list to find which element is connected to each side. But since the elements on Hypermesh don't have the same orientation, the whole process doesn't finish.. Can anyone help me with this? Thank you very much!
  13. Hello guys, I cannot import .prt file that it is exported from NX CAD. It show "UG version not supported". It is not working in any HM version. Any suggestion? Thank you in advance.
  14. Hello, I've been trying to connect two surfaces using area connectors but I can't seem to get it to work. I always get the following error: "Realized Elements are Double Dependent" I'm trying to connect the surfaces in white to the bottom one in blue. If I connect one of them first, the second will fail; If I connect both of them at the same time, they will both fail. The mesh on both the top (yellow) component and on the bottom (blue) component is perfectly symmetric. Can anyone help me please? Thank you very much!
  15. Hi All working on 3D flange having holes..i m trying to write script for 3D mesh of it.. process i am following is : 1. washer split for holes. 2. 2D Automesh surfaces 3.

  16. I 've downloaded the captioned tutorial pdf and .fem deck data from Altair Connect. Importing "Thermal.fem" finished sucessfully, but, At Step 5, There is no node numbered "4679". (I searched the node by ID, but HW shows "No change. Total selected 0." ) I would like to know how to find it or if there is specific setting of importing the .fem file. I am using Hypermesh v14. Thanks in advance,

    Unit of OptiStruct

    Hey guys! I saw one composite optimization tutorial where the units of the results were not S.I. (lbs, ft etc.). My question is: how can I modify the unit of my input parameters? So far I thought that Optistruct use mm, s, MPa, ton as unit and I have to calculate the conversions between different units of measure. Thanks for your answer in advance! Best regards, Imre

  22. Hi , I have large amount of nodal temperature loads applied on the model. Is there any way to visualize the temperature load using contour plots in hypermesh. Also , incase of PLOAD cards applied on the elements. Can we visualize applied pressure in hypermesh using contour plots? Thanks in advance. Girish
  23. Hello guys, I'm now trying to remesh my model via hypermesh. Let me briefly introduce my research process. I had a framework elastomer sample, and I sent it to do the microCT scanning. After some post analysis, I got a .stl file which is meshed by the vertices and edges. However, the mesh from .stl itself are not what I want. There are too many elements and the quality is bad that cause my abaqus not responding. Is there any methods that I can remesh my existed .stl file via hypermesh? Thanks a lot~
  24. Hi. I am new to this software and i got an error which read: *** ERROR # 1000 *** in the input data: Incorrect data in field # 4. The element in question is a CTRIA element.
  25. Hi every one. I was working for a 3D model, where i want to assign the composite material like e-glass epoxy with different fiber angles at different regions (for example like leaf springs). I wanted it to do with 3D elements, with including the contact non linearity. Can it possible, i have done for 2D elements by creating the plys and assigning the thickness. but looking forward to do over with 3D elements. please suggest. Thanks & regards,
