  1. Hi, Please how can i see the curve ( itérations ) of my objective function in hyperview after a topology optimization ? I THINK THAT WE CAN USE THE FILE .MVW but i dont know how exactly Thank you
  2. Dear all, I'm working with HyperGraph 2017.2 on a Windows 10 desktop PC. I would like to plot a curve in Hypergraph and color the shaded area under the line. Via Google I have found this link, where it seems that there is a check box available from the Curve attributes panel on the Line attributes tab. However, this check box seems to be missing for my Hypergraph: Does anyone have an idea how to solve this? (Or any other method to color the area under the line?) Kind regards, Robbin
  3. Hello there, I need some advice for defining the stiffness of a spring damper element with a curve. My task is to model a 1 mass oscillator with a non-linear stiffness. But first of all I want to understand how to define a stiffness through a curve. So I tried to model a linear stiffness through the curve and verify it with the regular linear simulation. My questions are: Can anybody tell me what I have done wrong with my curve definition? I defined a sinusodial force with +/- 10kN but the mass is just swinging in the negative area? Can anybody specify what the independent variable is? What do I have to put there when my curve is defined as force over displacement? I have attached my files. I appreciate every help
  4. Hello, I am trying to build a rigid mbd model with rigid bodies engaging in 2D rigid-to-rigid contact. I have defined curves where the contacts will occur, using the Add Curve functionality. Attached images 1.png, 2.png and 3.png from my curve panel, showing the settings I am using for all three contact curves. As you can see, in the Z direction, they all have the same value as 0. So they are indeed coplanar as they all line on the XY plane. I proceed to define a 2D rigid-to-ridig contact. Attached image, contact.png, shows my settings for one of the contacts I use. I have also made sure to correctly define the contact sides; so there are no problems there either. Finally, attached image, error.png, shows two of the error messages I'm getting. All my error messages are the same so I am only showing those two. It is telling me my curve graphics are not coplanar. However, what it seems is that they actually are indeed coplanar. I would be grateful for any help to fix this problem. Best regards

    Flip Crv Direction

    I did a curve blend between the start and end of a single curve. The direction of the blend was opposite the crv and confused the caps on the extrusion. Is there an easy way to flip it's direction?
  6. Hi there, When defining the stress-strain curve for the material (/MAT36), should it be used the true curve or the engineering one? Thanks
  7. Hello iam looking for a code to put all names on page 1 to an Array. It should save Redundant values only once a time. Has anybody a idea how? best regards
  8. Hello Everyone, I was looking for support with my FEA model. I don't have any pictures at the moment but hopefully I can explain what's going on and get some models/pictures later. Problem Statement: A curved beam with section centroid at a 6 in radius from a centerline spans 180 degrees and is fixed at one end while an 8000 in-lb moment is applied at the other. What are the stresses on the inside and the outside of the beam? Compare rectangular, circular, and trapezoidal sections with constant cross sectional area. Approach: I imported the arc from a simple iges definition file. I then line mesh with PBEAM elements. Cross sections have been defined correctly in the beamsection collector. Steel material has been generated. Properties for the sections have been created. This property is assigned to the mesh. Loads are put in their separate SPC and MOMENT load collectors. These collectors are passed to the SPC and LOAD parameters of the load step. Optistruct runs and produces the h3d file. Results: For some reason the stress at recovery points C and E for all elements are equal. This doesn't seem right to me. I would like to think that not only would the stress vary from recovery point C to E, but it would also vary (and increase) as the constraint is approached. However, the displacement of the elements and magnitude of said displacement DOES look correct. Can anyone provide insight as to why the SAMAX and SAMIN are equal for all the elements in this mesh? Thanks. EDIT: I've uploaded the result. The BCs are fully fixed on one end and 8000 (in-lbf) applied to the other end. Element is CBEAM with round section of radius 0.97. I'm using units system inch-slug-second. Can anyone help me out here? I'd upload the model file as well but apparently I'm not permitted to upload it.

    Section Average on Curves

    Hi, i want to include an average level line on specific sections of curves in my plot window, like in the attached Image. Is there some funtion / plot macro to do this?
