  1. Dear Support Team, I use Hypermesh and Optistruct to build flexbody models to use in MSC Adams MBD models. Since my flexbody models are large and have too many unused DOFs, I need to reduce them only to ASET DOFs. In the particular problem I'm trying to solve, I have a machine part with a few ASETs to attach/constrain it and a single location where I get response data from. So, the only DOFs I need are the DOFs of this response location (in addition to the DOFs of other ASETs). I can put an ASET on this location but I don't know how to force Optistruct to output only ASET DOFs to the generated Adams MNF file. In the docs for Optistruct MODEL solver card, Comment #1 states that: "For CMS superelements output in h3d format, only the ASET DOF are output when the MODEL data is not present." I need this same effect but with MNF format and not h3d format, since I work with MSC Adams and not Motion View. I have tried a few ways on my own but have been unable to succeed. Any help would be greatly appreciated. Best regards.

    Revolute Joint

    Can I model a revolute joint with HyperMesh? If so, how to do this? Does any tutorial show this?

    Force Label

    Hello guys, I am building a small size model with many forces close to each other, and there is a white label "FORCE" next to the red arrow that is the force applied. For the publication, I need diagrams with a clear view of the arrows, and that is impossible due to all the force labels overlapping each other. I have tried a lot of settings but that white force label will not disappear. Any ideas? Thanks! PS: the "label loads" option in the forces menu does not affect said label, it only adds the magnitude of the force next to the "FORCE" label.

    spring-damper model

    Hello, could anyone help me to create the mass-spring-damper models in optistruct?
  6. Hello guys, I tried the tutorial "HS-1545: DOE and Optimization Study with HyperMesh, HyperStudy, and ANSYS CFX" and it worked very well. Now I want to use a .msh file instead of the model.cas file. I thought there should be no problem because it is also a fluent-file. So I created a new study and went through the steps of the setup. When I reached the "evalute" step HS was able to write the Input files. But when HS wanted to execute it shows me always the attached picture. Is it possible to change some terms in the responsible files to avoid this error? Or is it just impossible to use a .msh file?
  7. I use Feko version 14.0.432 and try to design SMA connector. But I don't know how to add source port. Please advise.

    mass-spring-damper system dynamic analysis

    Hello, I would like to know how I can simulate/model a mass-spring-damper system in HyperMesh to do a dynamic analysis and get system responses and FRF in acceleration?

    Mesh component deleted, problems arise

    I obtained a download of an inhomogeneous human head model which was pre-meshed, from the looks of it. This model includes an "airbox" surrounding the human. Here's an image with a cutplane on top of the airbox to see the human inside: I wish to place a source near the head to simulate the near fields, but placing anything inside the airbox will cause errors since the meshes of the source will interfere with the mesh of the "airbox." Naturally, I tried simply deleting the airbox and re-simulating, but this error appears: Also, the downloaded human model seems to be of a different type than a normal created construction, since I see a different blue icon to the left of the model's material items: Has anyone run into this issue before? I can't place a source in the airbox mesh, and I can't delete the mesh without ruining the model for some reason. Any ideas? Thanks, Drew
  10. How do I delete a model that's loaded in one of the hyperview windows? Under the 'Session' tab on the left there is an option to delete a page, but I'm unable to unload/delete one single model that's already open in one of the windows.
  11. Hi All, I have set up a model of a pipe section and tried to subject it to torsion. The analysis completes but I have some unexpected results. I would expect the stress to be circumferential rather than axial. Have I set up the model incorrectly? https://www.dropbox.com/sh/rz0mgw3t1h91axq/AACnBNA5HjrX8AGIwFcpbQo3a?dl=0 Thank you Luke

    Issue with VWT

    Hi, I am very new to Virtual Wind Tunnel and Hyperworks in general, been at it for a mere few days, so my issue may be incredibly basic. My issue; I am using Solidworks to create a car model assembly, importing that into Hypermesh and meshing it. Everything seems to go correctly here. I am then importing the meshed file into Virtual Wind Tunnel, setting everything up and running the simulation. My issues comes with the results; it is 'seeing' my model as a number of dots/mesh elements, not as the whole model (I have attached a screenshot, poor quality but it gets my issue across). This could well be an issue with my model or meshing but I really have no idea. I have tried lots of things over the past couple of days to no avail. Any help would be greatly appreciated. Tim
  13. Our bolts, nuts, and washers, have part numbers where the letter m is either the second or third character. All of the other characters are numerals. How can I delete *m* collectors? I want to get rid of all of my bolts, nuts, and washers quickly. I do want a chance to review them first and make sure I haven't accidently somehow included a desireable part. Then after the review, delete them all! I am using HM 12.0 on Windows 7 on an HP computer. Thank you. Phil
