  1. Bonjour Bastien, Do you see a specific error message if you click on the red flag? Thanks, Matthieu
  2. When defining your cast part, click on the material icon Then go to the My Materials tab to create your won material.
  3. Uri, If you import your filter from the CAD, you can use its real shape: Inside the housing (diameter filter < diameter channel): not the best solution because the metal can by-pass the filter Exactly with hosing walls (diameter filter = diameter channel): the best solution Outside housing walls (diameter filter > diameter channel): the metal is slowed down as the filter is filled first and once it is saturated the metal can flow. I hope this helps. Matthieu
  4. The latest version is Inspire 2019.0.1 and we improved graphics a lot. Usage of VMWare can also be an issue for graphics bugs during picking. Unfortunately this is not supported on MAC and will require that you switch to a Windows machine.
  5. Which version of Inspire are you using? What is the version of your graphics drivers?
  6. HI Alberto, Please let us know your graphics card model and drivers version. Thanks, Matthieu
  7. Click2Cast used STL files. Inspire Cast is a different interface with much more functionalities that works with geometry. I hope this helps.
  8. Inspire Cast needs a geometry to setup a problem. Since STL is not geometry but mesh, Inspire Cast pops up the window so that you can import a geometry to work on.
  9. Hello, It takes more or less the same time for me on 2019. Thanks.
  10. Hello, Something is wrong in your setup that causes the solver to take a very long time to converge. On my machine it takes 5 minutes to solve on 4 cores. Thanks, Matthieu
  11. Hello, This is most likely due to the same kind of problems you have with your other meshing error and I would recommend the same methodology: Run Part only for solidification Add cores and run for solidification Add risers and run for solidification Add sleeves and run for solidification Add chillers and run for solidification Add Running systems and run for solidification Add Gate and run for filling By going progressively you can find out which component is creating the issue. Then the issue can come from either bad geometry itself or interface between components i.e. small gaps between components that cause the mesh to fail for the mold. Thanks, Matthieu
  12. Meshing errors are usually due to issues in geometry. Here is the process to find which geometry needs to be corrected: Run Part only for solidification Add cores and run for solidification Add risers and run for solidification Add sleeves and run for solidification Add chillers and run for solidification Add Running systems and run for solidification Add Gate and run for filling By going progressively you can find out which component is creating the issue. Then the issue can come from either bad geometry itself or interface between components i.e. small gaps between components that cause the mesh to fail for the mold.
  13. Hello, Solving time will depend on many parameters such as complexity of the geometry, element size chosen, velocity (could make the solver converge slower), casting process, ... Which tutorial model are you using and how much time does it take? Thanks, Matthieu
  14. The pahse change point is typically placed at the end of the runner, before the material reached the part. The piston starts to push the metal with low velocity (1st velocity) in order to avoid turbulence and formation of bubbles. Before the material enters into the part, the velocity changes (2nd velocity) and the piston push very fast the material to fill the full cavity. You can use Inspire Cast to experiment various positions of the point and see the impact on the quality of your part.
  15. Hello, Welcome to Inspire Cast. Here is an excerpt from our user manual available from the File > Help menu: Thanks, Matthieu
  16. Hello, Could you please let us know the exact model of your graphics card as well as your drivers version? If you have 2 cards on your machine, could you please check that the high-end graphics card is active? Thanks, Matthieu
  17. Hi, If you look in Altair Inspire Cast 2019 tutorials, you will find one named Low Pressure Die Casting which shows how to simulate a rim under LPDC. Matthieu
  18. Thanks. I could reproduce your issue and will report it to our development team. Please note that as a workaround you can save to version 5 to avoid this issue: save(zzz,'-v5');
  19. This is because Notepad can only properly display files with Windows newline (CR+LF). The code you use produces UNIX newline (LF only). In Notepad++, you can control which end-of-line is used in your file by going to Edit > EOL Conversion. The greyed entry is your current end-of-line. To make Compose write a Windows EOL, that will be displayed as you expect in Notepad, please use the following code: file = 'read3.txt'; fid = fopen(file, 'w'); AA=[1,2;3,4;5,6]; for i=1:3 fprintf(fid,'%f %f \r\n', AA(i,:)); end fclose(fid);
  20. Hello, A zero mass part indicates a part that is not solid. Please use the Patch tool to check if there is an opening in your solid that makes our geometry being a shell only. You can use this same tool to close that gap and convert your geometry to a solid. Matthieu
  21. Hi, This is an issue with Compose 2017.3 which will be fixed in the next release. Thanks, Matthieu
  22. Hi, This works if both are in the same file. I was referring to the function being in one file and the call in a different one. How can I include the first file in the second one? Thanks, Matthieu
  23. Hello, If I define a function in an OML file, how can I call that function from another OML file? Thanks, Matthieu
  24. Hello, Please have a look at this post on the solidThinking forum and let us know if it helps with your issue. Matthieu
