  1. Please, help me: I want to optimize a model. I am using Matlab for the optimization, Hypermesh as a pre-processor for my model and Abaqus as my FEA solver. I want to control all the operations in Matlab. I don't want to open Hypermesh and Abaqus. I have found a way around Abaqus. But I am having a challenge with Hypermesh. Directly from Matlab command, I want to call Hypermesh to execute my TCL script and output Abaqus input file. I want to run this process for many iterations by changing my mesh size in TCL script, thereby generating Abaqus input files of different mesh sizes. This is my Matlab script for Hypermesh: clear all; clc; hypermesh_bin='C:\Program Files\Altair\2017\hm\bin\win64\'; %enter the directory for the hypermesh executible cd(hypermesh_bin); run Hypermesh dos ('C:\Program Files\Altair\2017\hm\bin\win64\hmopengl.exe&') % run .tcl file (the name of my tcl file is comm) dos_command = ['hmbatch-tcl' , 'C:\Program Files\Altair\2017\hm\bin\win64\comm.tcl']; dos (dos_command) I am getting this error: ans = 0 The filename, directory name, or volume label syntax is incorrect. ans = 1 Please, help me: kindly tell me what I am doing wrong. Also, in order for us to have more discussion, I will appreciate it if you can send me an email, if you have worked with hypermesh directly from Matlab or you know how to do it. My email address is: sasamuelayinde@gmail.com Thank you.
  2. Hi everyone am working in Hypermesh(Aerospace) profile, i want to import load from excel which has nodal coordinates(or Element ID) and XYZ component forces . How to do this?? Thanks.
  3. Hallo, i want to convert an abaqus modell to an optistruct modell via the hypermesh convert makro. With most of the entities it works fine, but with some not. For example the section properties especially the beam section, connector section and solid section cards are not supported in conversion. The abaqus modell was build up in ansa and now I want to do a topology optimization in hypermesh optistruct. How can I handle this problem? Are there any configuration files for those or any other not supported cards and where can I find them? Thank you in advance. MT

  5. how to set and read two values in one variable using TCl?
  6. Hello everyone, i just want to know how to see the shear stress in tau_xy and tau_xz direction. I used optistructe as my solver. I only see "max shear" as an option but the result didnt expect as it shoud. the modell is loaded with a lateral force and has a fixed joint.
  7. Hey guys, I'm writing a script, where I can set a value (e.g. for the Young's Modulus) for a material property. My problem is that I would like to have a default value in the window, like 210000 MPa, which I can take and proceed or change it if it doesn't suit my material. Is it somehow possible to set such a default value? Kind regards and thanks in advance Simon Attached you can find the part of my script and a screenshot of the window I'm talking about: *startnotehistorystate {Modified E of material} set youngs_modulus [hm_getfloat "Youngs Modulus (Steel)=" "Enter Youngs Modulus:"] *setvalue mats id=1 STATUS=1 1= $youngs_modulus *endnotehistorystate {Modified E of material}
  8. Hey guys, as the title already says I'm looking for a macro which saves the nodes of a whole component into a nodelist automatically. In the end the command *plotnodelist is used and needs a nodelist to execute the program. Do you have any ideas how this could work? Kind regards and thanks in advance, Simon
  9. Hey guys, I want to create several materials, properties and components automatically. The desired IDs of all the materials, properties and components are saved in an external file and then written into a variable. Each of these values should create an own material, an own property and an own component. For creating the first material, everything works fine. But when the second material should be created, an error is occurring. Do you have an idea how this problem can be fixed? Kind regards Simon Attached, you can find the file with the IDs (these are the values in column 1 saved into the variable "field1") and the .tcl-script I'm talking about. SKO_3.tcl SKO.strs
  10. 空間内にシェル要素による構造物があるモデルで構造ー音響連成解析を行う場合、音響空間のソリッドモデルは図1のようにシェルを挟んで分離させておく必要があります。構造と音響の連成は音響モデルの表面で行われるためです。単にソリッド要素の音響モデルの中にシェル要素の構造モデルが埋め込まれているだけでは連成されませんので注意してください。このようなモデルを作成するのは従来は非常に面倒でしたが、HyperMeshにはdetach from wallという機能が組み込まれており、簡単に分離させることが可能です。HyperMeshリファレンスガイドの抜粋(detach.pdf)のP2にこの機能の概要が記されています。 detach.pdf
  11. Hi.... I have switched from Hypermesh 12.0 to 14.0 but having a problem in exporting the property name in Nastran (Long Format) and opening in ANSA. The names are retained in the standard format but they becomes default when I export the model in the Long Format of Nastran in HM 14.0 and open in ANSA software. I have never faced such problem in 12.0. Kindly suggest the solution. Thanks
  12. Hello All, I'm writing a journal paper and am planning to cite Hypermesh as a software used. How do I fill in the details for Hypermesh? Please help. The details required are attached herewith.
  13. Hey guys, is there a way to create a label in the utility menu? I only find command to create buttons etc., but no command for labels. Can you help me out somehow? Kind regards Simon
  14. Hi all, How to get nodes from free edges and drag it in particular direction using tcl? Regards, Sanket
  15. Hey guys, I'm trying to customize the output of a load step. Trying to run again the relevant parts of the command file, an error is occurring in this line. *startnotehistorystate {Updated string array} *setvalue loadsteps id=1 STATUS=2 4873={ } ROW=0 *endnotehistorystate {Updated string array} I'm pretty sure the empty brackets are the reason for the error, but I don't know how to get around them. Could you help me out with this problem? Kind regards Simon Attached you'll find my code. The relevant part starts after line 254. SKO_2.tcl
  16. Hey guys, after I have finished my work on a model, I start a new session in HyperMesh and want to delete the .fem-File from the previous model. This is not working, and a message appears saying that the .fem-file is still open in HyperMesh. If the command "file delete" is used, an error is occurring which says "permission denied". Do you know how I can solve this problem and delete the .fem-File without closing HyperMesh totally? Kind regards Simon
  17. I'd like to share the seamless integration that Compose with other HyperWorks applications, such as HyperMesh and OptiStruct. In order to expose the Compose function to other HyperWorks applications, we need to register the function. This is done clicking on the right mouse button on Register Function in Compose: After this step, we may now see that the function has been registered under the same mouse click shown above under Show Registered Functions button. Once it is registered, we may now use it inside other HyperWorks softwares, and the function will be available without the need for closing and reopening the application of interest. Example in HyperMesh: Why Compose and HyperMesh? Matrix Browser queries and modifies HyperMesh and HyperView data entities without writing cumbersome TCL coding, along with a Math method developed in Compose. Example in HyperGraph: Why Compose and HyperGraph? Plotting capabilities of HyperGraph are expanded with Compose’s advanced functions and custom procedures developed by the user. Example in HyperView: Why Compose and HyperView? Advanced post-processing or special mathematical approaches may be applied directly on the model. Example in HyperStudy: Add a new output response Define a new expression Use your custom Compose function Why Compose and HyperStudy? User-defined functions to perform design exploration and optimization. Example in OptiStruct: Why Compose and OptiStruct? User-defined functions to perform optimization with DRESP3 card (desired response based on external files). Regards, Roberta

  20. Hello, I am quite new to hypermesh and I want to create simple solid beam which has a hole and then I want to move the hole. I have built the model in hypermesh and added all the constraints, I have tried morphing but it deformed my meshes while moving the hole by making my beam longer. Would you please help me about which modules I should use? I am currently trying to figure our hyperstudy parametrization
  21. hello guys, i am doing some AcuSolve tutorials by Engineering Solutions-AcuSolve. I have found some problems with the Transient-heat-transfer while using on HyperMesh-Engineering Solutions. Here they are: 1. I can not restart computing on Engineering Solutions: The mentioned simulation is transient, which require a restart computing base on the previous computed results ( Steady-state). but restart function seemed not intergrated in Engineering solution. 2. Cant assign multiplier function for inlet's temperature: to be more precise, the inlet temperature drop down in few seconds. but this cant be specify in HyperMesh-Engineering solutions. Does anyone know about this issues? Please help. For more informations, please ask. Appreciated!
  22. Hi all, I am creating a new script which detects joints between several components and identifies the start node and the end node. I show an example in the image below: I am able to detect all joints with the *findmark command, but I don't know how to identify the node which "starts" or "ends" the joint. The start/end nodes are those which have temp nodes in the image. Can anyone help me to do this? Any suggestion? Thanks in advance, Alex
  23. Hi, I am doing tensile test simulation in hyperworks using imposed velocity load collector, can anyone explain how to get forces in output results.
  24. Hi, i am working on my bachelor thesis at the moment, in which i need to simulate the heat transfer absorbed by a laser. Therefore i want to apply different heat fluxes which overlap and run only for 1 second. After 1 second i want the second heat flux to start and also run for only 1 second. How can i do this? Thanks, Erdinc
  25. I have a node selected using "*createentitypanel node" API, from which i can also get it's coordinates or ID, let's say (101, 123, 67) and ID as 123456. Now, this is located on a circumference of meshed component where on the same circumference there will be other grids as well. I want to have list of all nodes have Z value as 67. Is there any way to achieve so? What if i have radial and axial tolerances as well. Please note that the component is made up of only nodes and elements. Thanks in advance.
