  1. Hi, thank you very much for your reply. I would not have guessed that it's hidden there.
  2. Hi, is there a way to change the font size of the values in the legend? As far as I was able to research, this seems to only be possible for every other text type like Footer, Header, Title and Local Maximum for whatever reason.
  3. It looks like you're using nTop Platform to create your original geometry, correct? I recommend using a voxel grid with a very fine voxel size to discretize the TPMS body as the meshing algorithm in nTop has difficulties discretizing complex geometries like yours. Smoothen it, then use Mesh from Voxel Grid and export it as STL. Remesh in HyperMesh to create a volume mesh afterwards. Shrink wrap mesh won't help you in this case as noted by Adriano.
  4. Sure, would it be possible to send it to you in private?
  5. @Q.Nguyen-Dai On another note, what does this error message mean? It pops up when I try to create a tetra mesh. Is it due to poor 2d mesh quality or is it something else? Ok got it, apparently it was because of intersecting 2d-elements.
  6. Oooh alright There's no need, but thanks for the offer. I remembered that there's an option in nTop to create voxel meshes which allows for much better quality meshes with this type of geometry. Hooray for bad memory, it keeps life interesting!
  7. It is, however I don't quite get what you're trying to tell me. What do you mean by "subtract"?
  8. @Adriano A. Koga The image above doesn't show it, but there is an internal structure that doesn't get captured by a shrink wrap, unfortunately. Otherwise, it might indeed simplify the task. But I'll take a stab at SimLab, thanks for the hint. @Q.Nguyen-Dai Yes it is. My best bet is probably to generate a new mesh in nTop until it's acceptable since this is just a mess, but that might take just as long as repairing it manually.
  9. That would take far too long. Well, I'll see how to handle this.
  10. I did have a look already, more than one. Did you? Take a gander at the image below. Is there a way to remedy these kinds of elements in an automated way such that a tetrahedral mesh can be generated from them or not?
  11. Hi, is it possible to redefine the break angle for face selection? I've got an stl file of a part that needs boundary conditions on the inside of two holes. However, due to the stl file, the edges are not at a sharp 90 degree angle and when selecting the faces for a BC setup, the whole part gets highlighted. How can this be remedied?
  12. I know that it is generally not suited for FEA, but there is no other option. nTop is no common CAD program, if you take a look at the file you'll see that it's not a geometry that can be easily generated with a normal boundary representation modelling method which is why a mesh representation is the only way to go. Regardless of the nature of stl etc, what would be the best option in Hypermesh to get a tetra mesh? It doesn't even need to be pretty, it just has to run without element quality checks.
  13. Hi all, I've got two messy stl files exported from nTop with approximately 1 million tria elements and quite a few issues concerning connectivity, aspect ratio, warpage, intersecting etc. What's the best way to repair the mesh automatically? I've tried remeshing, smoothing, equivalence, rebuild etc but it either did not result in a satisfying mesh or took too long to finish. It's too much to do manually and the tutorials don't cover meshes this messed up. One of the meshes is attached to this post. Thanks in advance for your replies.
  14. I thank you very much for your input, it's a great help
  15. Thank you very much for your detailed response, this helps a lot already. Could you point me to a function or combination of functions that lets the user exclude a fixed number n of the highest values? For now, there seem to be less than 10 problematic elements. I'm thinking of something, but I'm very new to Hyperstudy and need to look up how it's done: 1. Sort the data source in new vector 2. Define n, fetch highest element ID of new vector 3. Pick all elements from 0 to highest_ID minus n Your solution is good, but when I think about it, not well applicable to my case since there might be other, non-problematic elements that might surpass this threshold and those would need to be reported in the data source. Renumbering is of course an option, but if other elements become problematic in some cases, it wouldn't be enough either.
