  1. Where are these nodes from?

    Hello, When I selected nodes,more nodes are selected,but I didn't create them.I am curious that where are they from?How can I select the nodes I wanted only?thank you.
  2. Hi all, Without making temp nodes to preserved nodes how come there are preserved nodes in model. Is it possible? Thanks, mahes
  3. sir, where can i find full vehicle file of taurus for crash in radioss forum?

  4. Hi , what is the command to select nodes by path?
  5. hi, hm_appendmark nodes 1 "by adjacent" Since nodes cant be marked by adjacent. But I need to get adjacent nodes . Is there anyway that I can use
  6. Beam with non unoform

    Hello I am just new in hyperwork. I want to do displacement analysis for non unofrom beam as shown below. i have 2 different cross section, i defined 2 hyperbeam, 2 properties and 2 component. i use 3 nodes and use cbeam to connect the nodes, the define load step use optistruc to solve analysis, but my analytical value and value that optistruc is obtained are different. i just thank that maybe i should use RBE2 in B, am I right?if yes how can i do that? If no, what is my fault. Big thanks
  7. Sets

    Is there any way to get the node between two nodes of a element by tcl command
  8. Hello , I am doing the structural analysis of the disc and i need to apply forces on a particular area ( where the calliper is attached) again and again with different element sizes. I want to enquire is there a way so that i can simply select the area (maybe a predefined surface or something ) and the software can pick up nodes in that particular area? Thanks
  9. Using the Probe Command - AFDEX

    Hello people, This post is about using the "Probe" command in AFDEX to directly pick the nodes of interest from the screen and know the values of state variables like Effective Stress, Effective Strain etc. 1.Open the simulation result file (Format: .a2dsrf for 2D and .a3dsrf for 3D, refer AFDEX File types for details) and select the parameter whose value needs to be probed from the post-processor window. In this example, effective stress is selected. 2. Click the "Probe" command from the tool window and select the node of interest. The probed value is displayed on the lower bottom of the screen. Let us know what you think and feel free to ask questions if you have any. Cheers from AFDEX Support Team!
  10. Contact pressure concentration

    Hi everyone, I'm trying to model a cylindrical section being held between a grip that tightens around it. When I look at each jaw however, I have a contact pressure concentration in one area and I can't seem to find out why. I'm using Optistruct V13 and I use the auto-contact tool to create the contacts between each component. I have checked for penetration between these components and there is none (there is between two other pieces but I do not look at these). I have quite a fine mesh as I'm looking at this specific area (mesh size 0.5mm). Does anyone know what I could do to get rid of this point? Could it be that these nodes are slightly irregular and 'sticking out' slightly from the component? Thank you for any help you may be able to give me!
  11. Distance between node and plane

    Hi there, Is it possible to track the distance between a node and a user-defined plane in hyperview? Thanks,
  12. Hello all, I am from a Geophysics background and I am attempting to use HyperMesh to generate a FE Mesh of some basic reservoirs containing different fracture or fault geometries I am trying to mesh a a simplified model of a reservoir (volume) with two embedded intersecting faults (surfaces). I attached a picture of my simple geometry to give you an idea. I need the finite element mesh for flow simulations, however the simulation requires that the triangle elements of the fracture surface have shared nodes with the tetrahedron elements of the volume. I was able to generate a mesh successfully, however it does not seem to have shared nodes because when I run my simulation there is no communication (fluid flow) between the fracture and the rest of the volume. Can anyone help me with this issue? Is there a particular setting that I need to use to ensure that there are shared nodes between the surface and volume elements. Currently, I mesh the surfaces first, using 'Create 2D AutoMesh' then create the volume around it and I mesh that using 'Tetra Mesh' I would greatly appreciate any feedback you can give on this. Thanks, Ariel
  13. As you can see in the picture, two forces are acting on single node, on review, I am able to view the magnitude of that force. How to find about the other force? and to which load collector it belongs to, and it magnitude and other info.? Thanks.
  14. Creating a List of Nodes

    HI All, I have a very large model which has a lot of rivet connections which I plan to model using CBUSH elements. In order to easily model this, I need a list of the nodes where the rivets are to connect. I've already created fixed points at these locations in the Geometry. The way I thought to create the list of nodes is to manually create nodes at the points and renumber them 1->X. Then mesh the parts and equivalence the nodes so that it keeps the lower node ID (my logic may be flawed as I'm new to Hyperworks and this is something that would work in PATRAN). I've tried this on a small scale test model. I created the nodes (which I believe are temporary nodes) by going Geom > Nodes > Points and selecting the fixed points. I've then meshed the part, but when I equivalence (either in edges or faces) it says 0 nodes found. I assume this is because the nodes I've created are temporary or geometry nodes and not related to the mesh. However, I've exported the model as a .bdf and both the temporary nodes and the mesh nodes are recorded. Thus I'm at a loss for why equivalencing is not working! Is there any way to create mesh nodes without actually meshing, or easily create a list of the nodes I need? Cheers
  15. Hi, I have two 3D parts in contact. I want to ensure matching nodes between the parts so that the contact is good in FE. How do I do that please. I am using tet elements. Thanks
  16. Different Mesh Type

    Hello I just downloaded the academic version of the program. I want to mesh a part with different mesh type than the already existed. For example i want to provided the locations of the nodes of the finite element, Can hyperworks provide that possiblity? Thank you in advance
  17. I am attempting to move the midside nodes to the quarter points to capture the 1/sqrt® singularity for a crack tip model. I have created nodes at the quarter points but cannot figure out how to move the midside nodes from the half point to the quarter point. I have tried using morph selecting the fixed nodes and moving nodes as well as node edit but have not had any luck. Does anyone know of a way to do this? Thank you, -Clay
