Hi all, I am trying to produce a script which lists displayed entities. Specifically, I am looking to write a script which displays all loadsteps, then creates a list of all loadcollectors, hides then reshows them and deletes all non-displayed loadcollectors. it seems a bit long winded but my model contains loadadd loadcollectors and when I come to delete unused loadcollectors it doesn't identify any... despite there being a good number which are in no way used. Cheers in advance Andy -
Hello, I'm trying to load an .hm file created with a Student Version of the HyperWorks 13.0 (using Optistruct) into a comercial version of HyperMesh, but the following message appears: "The file specified is not a hypermesh database". What should I do? Thank you. -
Hi All, When I try to map thicknesses to my mesh I get this error: I have selected a user profile and I have never seen this error before. Any help would be much appreciated!

Hi, I have a problem with my model because i doesnt show any optimization after i ran the calculation.Plus, the solver are empty and its only said that the job is completed. I'm using an Optistruct of my school which connected to the server i guess. Please help me.

hello, i am new to make scripts. i am trying to do a script to delete empty assemblies and sub assemblies in one action. i need a loop format of script to do this. but i dont know the structure. please help me out.

タイトルの通り既知の3つの節点を通る円の半径と中心座標をスクリプトで取得する方法を探しています。 3つの節点はユーザーが選択するものとして、その取得まではできているのですがそこからは数学的に算出するしかないでしょうか？ もし円の半径と中心座標を3つの節点から取得できるコマンド等ありましたら教えていただけると幸いです。

Hello, My doubt is about Hinge joint declaration in Optistruct: What is the difference between first and second grid? It has something to do with dependendent and independent nodes? Or the order in which i pick the nodes does not affect? Thank you!

hello im triying to do a topography optimizaiton using ERP as a response, and a minmax objective. when i try to solve it i got the following error: *** ERROR # 2148 *** Invalid design problem. All the sensitivities of response 1 (objective) are zero.

Hi All, I am selecting component using *createmarkpanel comps 1 " " ; Now i want to know selected component contains 2d 0r 3d element; Regards, PD -
Hello, I want to make a thermal simulation of a cooling plate in hyperworks with the AcuSolve Solver. The geometry would be this: Where an aluminium cooling plate (the grey solid) is in contact with a water flow (blue volume). The problem is that I can't get a mesh with coincident nodes between both volumes, taking into acount that for the AcuSolve simulation I need two surfaces in the interface between the solid and the liquid volume. Do you have any solution for it? Thanks in advance. -
Hello all, I've been trying to recreate the example problem seen here: https://connect.altair.com/CP/SA/training/self_paced/optimization/content/opt3/pdf/ex1a.pdf But with a couple of modifications: 1. I have written a script to run the model in batch mode, however, the script cannot handle RBEs at this point. I've substituted all RBEs with loads and constraints assigned directly to the surfaces, effectively creating tractions instead of RBEs. 2. The script meshes everything in tetra elements. Everything else should be the same (material definitions, boundary conditions, objective function, etc). I'm thinking that these two modifications shouldn't change the outcome very much, but maybe that's an incorrect assumption? I keep getting an error in Optistruct that the compliance is huge and optimization can't be performed. Any ideas as to why? The model is attached. Any help or guidance is greatly appreciated! vf0.3_min30_wcomp.mvw vf0.3_min30_wcomp_des.h3d vf0.3_min30_wcomp.hm vf0.3_min30_wcomp.fem vf0.3_min30_wcomp.log vf0.3_min30_wcomp_003.out

Essa linha clara são 4 elementos de viga que recebem uma força na vertical no centro deles, representam uma manga de eixo. O objetivo é analisar distribuição de tensão nas bandejas de suspensão, por isso é bem simplificado. O problema é que, com uso de RBE3, eles deformam dessa maneira aleatória. Agradeço desde já as respostas.

Hey Guys! I've just wondering, it is useful to apply second order element for composite in Hypermesh using Optistruct as a solver? I think the composite theories use pretty much linear approximation between layers that's why I'm asking this "silly" question. Thanks for answers in advance! Have a nice day, Imre ps.: if you have any good tutorial, books etc. for composite modeling I would be grateful if you can share with me! :)

Hello forum, I have been trying to capture the center line of any given pipe/tube. But I don't find any readily available API. So, how should I proceed so that I can create one for myself ? Regards, Brahmadev.

I need help defining the contact between the parts shown in the attached image. The solver is Abaqus. I have given tie constraint between 1st and 2nd part (both master and slave are selected as surface). these two parts should be like glued to each other and no separation between them. but the tie is not working as the 1st part is passing through the other. also, the 1d line element should move with the parts to which it is connected. thank you

Hey guys, I want to calculate the mass of my model using a tcl-script. Is there a simple command to do this? (I haven't found one yet.) If this is not the case, do you know another way how to solve this problem? Kind regards Simon

Hello I'm new to Hyperworks and would like to learn via tutorials, especially Optistuct and Hypermesh for ply and composite analysis and optimisation. I've found a .pdf file and heard about a skateboard tutorial but I can't find the tutorial files anywhere. I'm using Hyperworks 14 (non student edition, I believe). I would be happy if someone could help me with this. Pascal

Hello experts, I am hypermesh_optistruct user. i have heard about a new feature in OptiStruct 2018 named "initial stress". i have looked at some papers from Altair but all the information is about BULK-DATA in OptiStruct. There is nothing about "how to assign initial stress in HyperMesh interfaces" Can somebody help me? Appreciate any help. Thank you verymuch!

I am positioning a meshed model as per new CAD. However, I also want my systems to position. Is there any way to do so?

Hi, I am attempting to create lattice members using a 3D geometry, I have come across a paper (see attached, pages 3 and 4) that uses the mesh to create derivative bars and nodes, I'm wondering if anyone knows how this could be achieved within Hypermesh and would be willing to talk me through the process. Kind Regards, Laurence Finite-Element-Mesh_Based_Method_for_Modeling_and__(1).pdf

Hi, I have a structure made of 3d solid map hex mesh elements, ie. primitive unit cells (see primitive image attached). I have turned my hex mesh elements into bar2 elements. I would like to create a central node to the primitive unit cell and connect bar elements to this central node (see body centred cubic image). I know this will most likely be a TCL script problem but I'm not sure how the script would be written. I have successfully created the primitive unit cell and used config edit tool to create bar2 elements (CBEAM's) But I would now like to do this with elements connected to a central node. A comparison of what I'm attempting to do can be seen in this paper: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6265793/pdf/materials-11-02073.pdf I look forward to hearing from the community, Kind Regards, Laurence
