  1. Hello, I have a question regarding the presentation of results. Find attached two pictures of the same result presented in Inspire and Hyperview (from scratch directory. fem & h3d). You can see the result of a screw pretension. The stress distribution look extremely different and i'm a little bit surprising. Is there any reason for that? Best Regards, Mario Pretension.stmod
  2. Hi Felix, The asymmetry is not the problem, but the stress distribution does not look plausible. Corresponding to the pressure cone (area) of a screw connection, the highest load should occur at the top. Best Regards, Mario
  3. Hi Felix, Thank you for the explanation, now I can understand it. Unfortunately, this does not improve the plausibility of the result. Best Regards, Mario
  4. Hi again, The "Autocalculate Meshsize" of both parts is switched off and min. is 1mm, max is 5mm. There is nothing more to do, only run a calculation. If it is not comprehensibly, then i can send also results (but the file is much bigger, since you need also the h3d for Hyperview). Version i'm using is Inspire 2017.3.1 build 8625. Best Regards, Mario
  5. Hi, The file is already attached in the post. (Pretension.stmod) Best Regards, Mario
  6. Optimization Error

    Hello again, Here is an updated model and example optimization. Find attached the model file. The example is a topology optimization (objective: max. stiffness, % of space volume). Best Regards, Mario model0817_CleanUp.stmod
  7. Optimization Error

    Hello, I would consider the following things: The constraints and force are not connected to the solids (non design), since they are attached to free points. This will be the reason for the error message. All longitudinal and vertical inner beams are modeled twice There are a lot of intersections and so it is a problem to find clear contacts for the solver. You get a warning message before the run (in my version 2017.3) At all, try to model a flat solid plate between the two non design borders. Then you get a idea on how a optimized support structure looks. After clean up point 1 and 2, I could do a structural analysis (see attached picture). I did not try to perform an optimization, since it is useless for me. Best Regards, Mario
  8. align

    Hi Arjun, Thank you for the video, but the question is how to snap midpoints to midpoints (of edges)... Best Regards, Mario
  9. align

    Hello, you are right, my retangles had the same height. Then it snaps to the midpoint. If you want to snap at the top midpoint you have to move the local axes to this location first. My fail, sorry. Best Regards, Mario
  10. align

    Hello, you have to switch on the "Snap to midpoints (or press ALT)" snap option (all others off). Use the "Translate" tool to move the rectangle near the target location and it snaps to midpoint-midpoint. Best Regards, Mario
  11. FEM import scale

    Hello, This does not seem to be right. It seems Inspire read FE-models always in mm. Tested with HM2017 & Inspire 2017.1 It might be possible to add an option when importing to set the source units. Best Regards, Mario
  12. Slicing a solid body

    Hello, Yes. Use the "Cut Modify" Tool to slice solids by planes. See attached picture. Best Regards, Mario
  13. Inspire simple geometry creation

    Hello, I always press as the first action "new part", before I start sketching (flying icon on sketch). Try it please. Please check in the Model Browser, if a new part has been created? When you finish sketching, no part is selected. Be sure you select the right one. It is highlighted and you can select almost any geometry (Solid faces, surfaces and edges of surfaces). Best Regards, Mario
  14. Inspire won't run on my computer.

    Hello, Contact your support hotline and provide the configuration of your system. Replace your Intel Graphic hardware by something decent. This is a basic requirement ! Best Regards, Mario
  15. Flip Crv Direction

    Hello, try the following: Pick the "Blend Curve" Switch to "Edit Parameter" Mode At the control panel change "Continuity" to "Tangent (G1)" or Change "Tangent Direction" to "Free" and change the 3D tangent direction fully free Best Regards, Mario
  16. Failed Optimization (again!)

    Hello, I don't understand, why do you want to have a contact at the lower wall? My suggestion is to bound the part to the wall and fix the wall with support in all directions (no displacement constraints). Best Regards, Mario
  17. Drawing Lines at specific Lengths and Angles

    Hello, you can try the following (see attached picture): 1. Create a copy of the line 2. Use Transform->Rotate tool 3. Drag the center of rotation to new location (at example to the endpoint of the line) 4. Rotate, you can enter any value on the tool dialog Best Regards, Mario
  18. Hello, A possible solution is to define design and non-design spaces on your part. So you have always the original geometry of non-design spaces and can easily use PolyNurbs for the design space parts. Best Regards, Mario
  19. Hello, It is generally not recommended to apply loads at the design space. Define a non design space at the loaded outer sheets... Best Regards, Mario
  20. Supports in Inspire: Rotational constraint

    Hello, 1. You can constrain a full surface of course. You need the stripes only if you want to have local constraints. 2. You model have rigid body modes and is so far singular (since translation in Y are free). Rotations about Y are constrained, Rotations about X and Z are free at the moment. Best Regards, Mario
  21. Supports in Inspire: Rotational constraint

    Hello, since you have now constrained translation dofs on more then one row of nodes (all nodes on the small surface), the rotations are fixed by this translations. But try it, you will see ;-) Best Regards, Mario
  22. Centered Polycube

    Hello, I get the following for default "centered" polycube (ctrl+click). Is it a bug or feature? (Evolve 2016.1 build 5559 64 bit Windows 7) Best regards, Mario
  23. Centered Polycube

    Hello Arjun, tested it on 2016.2.6160 (Windows 7) and now it works correctly. Bug is gone ;-) Best regards, Mario
  24. Supports in Inspire: Rotational constraint

    It's very simple, you draw a simple line on the existent part. If you finishing the tool, this surface is splitted... Normal constrain is the standard constrain for solids, as you have shown in the first post. Since all nodes on the surface are constrained in translation, the rotations are also not possible (force pairs).
  25. Supports in Inspire: Rotational constraint

    Hello again, Try the following: select the line tool pick the face of interest draw "cut" line on this face exit line tool Best Regards, Mario
