  1. Hello, "Porosity" result shows the macro porosity as a percentage "Total shrinkage volume" shows the macro porosity as a volumetric value. "Micro Porosity" shows micro porosity as a percentage "Niyama" shows micro porosity as ((C*s)**0.5/mm)
  2. Hello, The acceptance of the porosity level will rely on where the porosity is (surface finished, leakages, structural regions ..) more than the size itself. Those standards are used by the companies to designate different porosity regions depending on the requirments from their components. hope this help.
  3. Hello, Niyama is just the thermal gradient divided by the square root of the cooling rate, and it helps to detect micro porosity. I attached a ppt where this is explained but basically the lower the niyama values (high cooling rate or low thermal gradient) the higher the possibility of micro porosity. Remember that Niyama works under a certain range depending on the different materials. This range is not necessary to know in Micro Porosity result. This result is based on dimensionless niyama so no range known is needed. This result is based on niyama and also in other parameters like pressure... (I attached a paper that talks about it) Best Regards Micro_Porosity.pptx 2008-5.6_nileakers.pdf
  4. Hello Brendan, Could you please upload this file you are having problems with to check what is happening? Best Regards
  5. Hello Oliwia, Could you please send us one of the models you are having problems to mesh? I would like to know if the problem is the software or the geometry. Thanks.
  6. Hola Iñaki, Parece que la licencia no está funcionando. Por favor, contáctame a mi email para ayudarte a solucionar el problema. Un saludo. ptorne@altair.com
  7. Hello Andy, you can use AlMg5, it is a similar alloy. Please, contact me if you need aditional info. ptorne@altair.com Best Regards
  8. Hi Uri, Inside the project folder you'll find different files (meshing files, geometry files, solver files...) Is there any file in particular you are interested in? I attached a document that explains how to run C2C in batch mode. Best Regards C2C_BackgroundRunning_v4.0.docx
  9. Hi Uri, This problem appears when the ingates are not well set. It looks like this is a second iteration of an initial simulation, maybe during the second selection of materials something got corrupted. When this happens I recommend to start again the simulation from the original stl creating a new project. Please find attached a simulation ready to run, please check the parameters are fine and run the simulation again. Best Regards ALL-FEED_1.gid.rar
  10. There is a problem when the ingate surface is in contact with one of the surfaces of the additional components (sleeve, core,..) Meanwhile, in case you have this situation, please extrude just an small offset of the face in order to separate the ingate surface from the sleeve surfaces. (see below image) We'll work to solve this issue. Please, find below a link to download the file with the ingate meshed. https://ftam1.altair.com/message/m40gPhijtxxbaxGThmKcbB Best Regards
  11. Hello Uri, The problem is there is no ingate on this model. Please, start again from the scratch and mesh again using an ingate. This should solve the problem. Best Regards
  12. Dear Uri, There is something wrong with the configuration of the sleeves but it's hard to know what's happening just with this error message. If you send us the project folder we can debug and try to find the error. https://ftam1.altair.com/filedrop/~LMxXrO Best Regards
  13. Hi Dinesh, Wheel rims are made by Gravity Casting or Low Pressure Die Casting processes. Both processes can be simulated in C2C. Please, take a look at the attached document. Exercises 2 and 3 talk about the setting up these processes. Feel free to contact us if you have any questions. Click2Cast_Training_4.1.pdf
  14. Hello Mario, Is this happening every time? Could you please try with a different model just to be sure that it isn't a problem of permissions? You can contact me to check this in a webmeeting. ptorne@altair.com
  15. Dear Otavio, It looks like there is a problem with the inlet. Could you please check the ingate has been well defined (check if it is inside the geometry and in the same plane) Please check too the element size, 1mm seems too small for this part. Best regards
