For shrinkage simulation
1 Attachment(s)
I want to simulate the shrinkage for gravity casting. I have the .stl file of the castings (shown in the attachment).
For flow3D, it cant allow use multi-mesh to simulate the shrinkage, but I want to use it, because it can conform the real situation. So how can I solve for this problem? |

Thank you. but i dont understand ifob()=5? how can i set it? i can upload the .stl file to you. Can i have any contact of you? My email address is : le.zhou@gkss.de Thank you very much! |

You need to define a new component with the shape of the region you want to deactivate and call it Domain Removing in the GUI, which translates to the setting of IFOB(n)=5 for that component #n. All cells blocked by this component will be deactivated. How come you are using such an old version of FLOW-3D? |

Thanks your replying! and i have another question, that is how can i model thermal stress using elastic model. I read a paper about the hot tearing, the author used the Magama software to simulate the hot tearing and the damage. they cna get the vov mise stress, and other data which is useful prediction the hot tearing susceptibility. |

because of limited of upload, i cant upload the paper for you , so i list the name of the paper: prediction of hot tear formation ina magnesium alloy permanent mold cating. This is subject of my PhD, so i really want helo from you. I think flow3d can do it also. Thank you very much! |
Hi Zhou,
There is not enough room on thvis forum to explain such a broad topic as modeling stresses and strains in FLOW-3D. This capability has become available in version 9.2. I suggest contacting your FLOW-3D support to get the information. |
