  1. I'm looking for other software that can turn a lattice optimized model from HyperMesh, to a printable .stl file other than 3-MaticSTL. Preferably opensource/ free. We don't have the partner alliance software and so don't have Materialize software. Any help appreciated. Thanks
  2. Thanks but I've found out it isn't a ASCII or binary problem anymore. If I drastically reduce the file size using loose shrink wrap, I can save it as an STL file. I'm not sure why it can save only small stl files. EDIT: Does anyone know how to export large files as STL? It just doesn't seem to want to do it
  3. I want to export to STL binary, is this possible in hypermesh? I am trying to send an STL file of my model to a friend. When I export it as STL I can't open in other software to see if the file works. These include SolidThinking and even HyperMesh itself!!! When trying to open the STL ascii file in SolidThinking it doesn't work, is this because it's in ascii file? An error file comes up saying "save invalid elements to usermark?". It is quite a large file (8.1MB), is this the problem? Also, I want to export geometry as a STEP file but it can't saying "no geometric entities present for export". Any help is much appriciated
  4. For all those trying to do the same, this is how I managed to select a surface area of nodes: Right click in command window > create > set. Change the card image to MBPCRV then click on '0 nodes' > nodes (yellow). Now go to your surface and hold shift + left click. You can choose to pick a square, circle or polygon surface area of nodes! For some reason this wasn't mentioned in the introductory tutorials
  5. Yes I've tried 'all' and 'displayed' but both don't work. While it's processing, the feedback text at the bottom left of the screen says '0 elements processed', '0 CTETRA elements processed', '0 nodes processed' and other messages including an error message but they pop-up too quickly to read. I am trying to simply follow this tutorial (http://training.altairuniversity.com/optimization/topology/toplogy-optimization-basic/) but for a PSOLID instead of PSHELL. I have watched all the videos twice and still can't find out the problem with my model. It just gives me results for an analysis instead of optimization
  6. Hi all, I've been trying forever to delete this floating particle without luck. Im pretty certain it is lines and points (rather than elements and nodes). Anyone know how to?
  7. I have attempted to do that except with nodes instead of elements, but my problem is that I´m not sure if the software is capable of selecting a surface area. I can obviously select individual surface nodes one at a time, but this would obviously take a long time. I´ve also managed to select many nodes in a line by using the "by path" function of selecting nodes (which is effectively 1 dimensional). But is there a function for selecting a 2D surface area on the outer surface of the bone?
  8. I am trying to model the forces applied upon a Jaw, in a simplified study. I am trying to pick a small surface area on the bone where the muscle attaches, to model the force. In the picture screenshot you can see the blue area where the muscle "insertion" is. This is approximately the surface area I´d like to select. I´d like to map this area onto my solid mesh in hypermesh and then apply a force to it. There are other constraints in the model that require a surface area to be constrained (such as the top surfaces of the molar teeth) but if I can do one then I can do them all. I´ve tried using surface edit, solid edit, etc with no luck. Perhaps I am doing them wrong. If anyone knows how to do this, providing simple steps would be very handy as I don´t have much experience with HyperWorks and the userface is pretty trickey. I plan on using OpiStruct for analysis after. I´ve looked all over the internet with no luck so far
