  5. Frequency Response Analysis

    I am new to frequnecy response analysis and have some queries regrding the same 1. I referred the OS- 1300 module for frquency response and I am not sure about how the values of COUPMASS and WTMASS was taken. 2. I want to apply the base excitation of 1g to my model. How can I do that? 3. In the tutorial the DAREA is applied and dof3 is given value of 20. Does that mean the application of frequnecy with amplitude 20? 4. How can I give the damping of 1% to my system? Thank You.
  6. The installation works correctly, I've tried running as administrator, reinstalling, uninstalling, rebooting, running with and without the license file. The program loads for a moment and them the process just dies, sometimes windows says there was an error, others it just fails. It does install the program and I can open the help files and license manager, but the programs themselves, FEKO, POSTFEKO and CADFEKO don't open. This is a windows 7 64bit PC with 32Gb of ram. What could be causing this, and how to fix it? Any help is highly appreciated!

  13. How can I submit a job to abaqus through the Main console in HyperMesh, I tried using abaqus job=abc.inp (for example), however HyperMesh gets stuck there and a few minutes later I get a Not Responding and have to shut down HyperMesh then. Thank you.
  14. What is ESAComp ?

    ESAComp is software for analysis and design of composites. Its scope ranges from conceptual and preliminary design of layered composite structures to analyses of details. ESAComp is a stand-alone software tool, but thanks to its ability to interface with widely used finite element software packages, ESAComp fits seamlessly into the design process. The comprehensive material database of ESAComp forms the basis for design studies. ESAComp has a vast set of analysis capabilities for solid/sandwich laminates and for micromechanical analyses. It further includes analysis tools for structural elements: flat and curved panels, stiffened panels, beams and columns, bonded and mechanical joints. ESAComp is developed and supported by Componeering Inc., Finland. www.esacomp.com or check out our Altair Partner page http://www.altairhyperworks.com/partner/ESAComp ESAComp-Intro.pdf
  15. Batch Mode

    Hi there, I am trying to load a tcl script from the command prompt using batch mode that does a bit of post processing. When i run it, the command prompt doesn't produce any errors however once it is complete HyperWorks has not loaded and I can not see my results. Is there something additional that i need to add to the command prompt line or to my script? Command Prompt line: C:/altair/hw/bin/win64/hw.exe -b -tcl "<tcl_directory" "<tpl_directory_called_in_tcl_script>" `

  17. Helicopter Rotor Critical RPM

    Hello Guys, I have a working model of a composite helicopter blade. I have extracted the modal frequencies of the blade. I want to know if there is a way to find out at what rotational speeds will the blade reach any of those modal frequencies? is there a way to do this on hyperworks? Kind Regards, Mohamed
  18. Hi, I have created a session file where it generates graph between strain and stress for a particular element id. Now i would like to change the element id and reuse the template or session file. I am very new to hyperworks and have no idea how to change .tpl to tcl script or .mvw to tcl. For understanding i am attching the images created by saved template and also the template. I would like to create a script such that it should ask me to enter the element id in hyperview. Any suggestions or recomendations (example scripts) would be verymuch appreciated and helpful. Thanks in advance Agassi e181115.tpl
  19. Hello! I am a student and still new to the program. I am currently working on the C-Clip Tutorial and when trying to use Optistruct, the Solver View is completely empty. All the panels are empty and the summary only reads " ===Job complete=== ", nothing else. And when I try to use HyperView next, I don't see anything either, it is empty, too. Panels such as the folder directory for the model and results are empty and I can't manage to open the files manually either. I will add an screenshot of the Solver View. Please note: I am using a PC which doesn't save the data locally, but on a server, which can be accessed from various PCs in the university's laboratory.
  20. Hello, I'm using HyperWorks 13.0 Student Edition and suddenly a hm file started to take minutes to open or to edit anything (specially surfaces). When I try to mesh something the program enter the mode "Not responding". What is that? What should I do? I've already tried to save as another file, to import then save, to restart my computer, to clean my temporary files, etc... But i think that the model has some problem. Thank you.
  21. Failure to get h3d file

    Hello! I have this problem of not getting the h3d file. After meshing my component and applying the MPCLL , I went for the free free run and then i got the message ANALYSIS COMPLETED Then when i went on for RESULTS , I got this (attachment attached) message stating "UNABLE TO LOCATE .H3D MODEL FILE" Please help me in this context .
  22. Hello, I'm trying to import a .prt model into my HyperWorks but the only file types that are "recognized" by the software are IGES, SolidWorks and STEP. How can I fix this? I'm using HyperWorks 13.0 Student Edition. Thank you.
  23. Hi, I am currently working on creating a macro just to learn the process. I want this macro to check the components and see if a component labeled "^2D" exists. If it does not, I want the macro to create this component. The macro will then move all 2D quad and tria elements to this collector. The reason for this is I like to save my 2D mesh in a collector that I can turn export off before output to a .inp. I have used this code to verify that I am able to create the collector and move the elements: *beginmacro("Move2D") *createentity(comps,name=^2D) *createmark(element,1) "by config" tria3, tria6, quad4, quad8 *movemark(elements,1,"^2D") *endmacro() However I am having trouble when attempting to do a loop check. I am 99% sure that my formatting for Tcl is completely wrong (I just began learning the code yesterday). When attempting to load the userpage.mac hyperworks freezes with the code how it is. *beginmacro("Move2D") set exists "False" set entitylist (hm_entitylist comps name) foreach title $entitylist { if {$title == "^2D"} { set exists "True" return } if {$exists == "True"} { *createentity(comps,name=^2D) } *createmark(element,1) "by config" tria3, tria6, quad4, quad8 *movemark(elements,1,"^2D") } *endmacro() Thank you in advance for any help, -Clay
  24. 3PB Impact Test

    Hi there, I m trying to validate a 3 point bending simulation using a paper which presents both numerical and experimental data. I followed the exact same setup but the resultant force I keep getting is always 20% smaller than the one pretended. I've double-checked materials, properties, contacts and boundary conditions and nothing seems to change. I've tried the validation process with different papers and I always get the same problem. Any idea on what I might be doing wrong? Thanks,
