  1. We strongly recommend using sT inspire (given free for students) for basic FEA,
  2. can you put up an image of the connection between hex and quad etc to explain better? you can extract faces tool > faces to create connected tria elements as a skin over the tetra elements.
  3. You will have to export to Abaqus .inp format , from file > export , after you have set the user profile to abaqus. If you are using the student edition, it is not possible to interface with abaqus.
  4. go to the line number that gives the error in notepad , See if the card specified in that line is supported, deleting the card may be necessary, Make sure your hyperworks installation has the latest updates installed.
  5. Also make sure the elements are of acceptable quality, go to tool > check elements and identify failing elements, save them and repair them using the repair tools. Remesh using a smaller element size, remesh problem areas etc refer the student guide for more details - http://www.altairuniversity.com/free-ebooks-2/free-ebook-practical-aspects-of-finite-element-simulation-a-study-guide/
  6. Do you have import as include option unchecked in the import options section? please delete your settings files and make sure there are no include files in the folder where the input file is,
  7. make sure all the elements you are exporting are tria elements, only tria elements can be exported as .stl
  8. yes, you can open multiple windows of the student edition which serves the same purpose you are looking for.
  9. see HyperWorks Desktop Applications > HyperMesh > HyperMesh Tutorials > Meshing > 3-D Elements: HM-3220: Creating a Hexahedral Mesh using the Solid Map Function
  10. Use a small element size, with the lowest tetra growth rate, or user control the growth rate, make sure the checklist attached here is followed for the surface mesh before the tetramesh, HyperMesh02 (1).pdf
  11. See the tutorial here OptiStruct > OptiStruct Tutorials and Examples > Tutorials > Topology Optimization: OS-2010: Design Concept for an Automotive Control Arm where design and non design components are separated etc
  12. We have reported the issue to the developers, please try the same operation in the latest version and also provide us the version details, please also try the operation after deleting the setting files -
  13. I suggest you use minimum member size constraint and a higher one at that, You can always use minimize mass as the objective with required mass targets To use the previous optimized result as a starting point, use fit to fit a solid model onto the optimized model export it to CAD and smooth it > then bring it back to inspire for reoptimization.
  14. Each mode F should be in cycles / second i.e. hertz in my opinion, the deformation in m is just symbolic, you can go to the working directory and look for the .out file, then see http://forum.altairhyperworks.com/index.php?/topic/15947-frequency-units/#comment-28109
  15. You can go to check elements (F10) > duplicates > save failed > Mask (F5) > retrieve > mask > reverse > delete displayed elements, also Go to tools>>edge panel. Change the toggle to "elems" and select all the elements on the component. Preview equivalence and then equivalence the nodes.
  16. see - http://web.solidthinking.com/evolve_polynurbs_webinar In this webinar, you will learn: How to import an Inspire optimization into Evolve An introduction to the Evolve user interface How to use Evolve's polygonal modeling tools to recreate the part as a solid geometry How to use the Nurbify function in Evolve to convert polygons into solids How to export a solid geometry from Evolve
  17. Have you used OS Smooth already ? - OptiStruct > User's Guide > Design Interpretation - OSSmooth
  18. In general 1. INCLUDE commands may be placed at any location in the input file, but must include information appropriate to that location. 2. Names specified on the INCLUDE card can be arbitrary file names with optional paths appropriate to the operating system (Windows or UNIX). They may be enclosed in quotes (double or single quotes can be used), and either forward slash (/) or back slash (\) characters can be used to separate parts of the path name. The following rules are used to locate a file referenced on the INCLUDE card: • When the argument contains the absolute path of the file (if it starts with "/" on UNIX or a drive letter, such as "D:", on Windows, for example), the file at the given location is used. • When only the file prefix is given (without the path), the file has to be located in the same directory as the file containing the INCLUDE command. • When the argument contains a relative path (../filename or sub/filename, for example), it is located in the directory relative to the file containing the INCLUDE command and is NOT relative to the directory in which the solver was executed, or to the directory where the main file is located.
  19. See Free eBook: Crash Analysis With RADIOSS – A Study Guide http://www.altairuniversity.com/free-ebooks-2/free-ebook-crash-analysis-with-radioss-a-study-guide/
  20. You can use the temperatures panel to add temperature loads from a file HyperWorks Desktop Applications > HyperMesh > User's Guide > HyperMesh Panels > HyperMesh Panels Listed Alphabetically: Temperatures Panel Linear interpolation: Use this option this to interpolate pressures from a saved file or existing loads. Note: Linear interpolation only works with shell elements.
