Hi all
Dear FAr & Simon, both look ICEM CFD users. Could any one of you help me to generate my mesh. I attached my geometry in order to help. PLease. I try it many times but it comes wrong with me. I import the geometry using file/workbench readers and then set the boundaries and add material and do bloking and then spilt the block to capture the features of my geometry then do O-grid as well as, I associate the curves with necessary curves and then set the size of my mesh and then do pre-mesh finally I save the mesh as .uni file and open it to export the ansys cfx mesh (.msh). But all of that do not give me any good mesh. Please give me seruis hand to do.Or do it and send it to me via this mail sofarineed@gmail.com agdb.zip Best Regards |

Thanks Far
did you do hexa mesh or tetra one. Regards Safia |

[QUOTE=Far;400054]did you click on the project file to open it?
I am not getting such problem....[/QUOTE Dear FAR,,,, I got it. After I open I read the surface model of my geometry again with keeping the O-grid. It is working. BUT the inlet after meshing is square although I made it circular in design modeler file. So how I can deal with this issue. I want circular inlet nor square. Any comment can help. Best Regards |

Open the project file
If it does not load the tin and blk then manually add the files.(this may happen as I have renamed the .tin, .blk and .prj files and then zipped them) 1. First open the .tin file I have sent through zip 2. Read the corresponding .blk file. The inlet will be round |

Usage: define_curve [tetra_size %d] [name %s] [family %d] [width %d] [nlayers 269225800] [ratio %f] [min %f] [dev %f] (data on following lines) error executing command: define_curve error in room_safia_Far_O-grid.tin can't read surface model so I cannot see any thing. 2-when I open prj file it requests .tin and .blk files(both exist) but it requests the atr file too (not exist). even I do cancel I only see square inlet after mesing. did you draw the model using iCEM CFD or import my geometry on ICEM CFD? you have not a problem because you have all files. Really, I appreciate your help, and I wish if you help me solve this matter. Best RegardsUntitled.jpg Untitled2.jpg Last edited by happy; January 4, 2013 at 23:43. |

Could you please show me in details how you made your mesh? Some of that, I did it before and the rest still non-understandable. Is the release 14 only can handle this configuration? The cluster at my university has Re13 so that there are not benefits to do it in Re14(time cost). I would like to conduct my mesh and simulation using Re13 (no choice). So could you please show me in private a message? Your favor will not be forgeable. Regards |

HI FOR EVERY ONE
i HAVE PROBLEM WHEN I MESH MY GEOMETRY (QUARTER PIPE WITH ONE PERFORATION) BY HEXA MESH. WHEN I COMPLETED FROM MESH I SENT MY MESH TO CFX BUT CXF OBJECTED AND REFUSE TO COMPLETE THE SOLVER AND THE ERROR ISSUED AS BELOW. HOW CAN I TREAT THIS PROBLEM WITH SYMMETRY BECAUSE I HAVE VERTICAL SYMMETRY ( CONSIST FROM TWO SURFACE (ONE SMALL FOR PERFORATION AND THE OTHER ONE BELOW FROM IT I.E. TOUCH WITH THE UPPER ONE FOR THE PIPE) AND THE OTHER SYMMETRY HORIZONTAL ONE). I CAN'T MERGE THE UPPER ONE AND LOWER ONE. WHY THE CFX OBJECTED? HOW CAN I PASS THIS PROBLEM? ERROR #002100013 has occurred in subroutine Chk_Splane. | | Message: | | The symmetry boundary condition requires that the boundary patch | | mesh faces form a plane or axis. However, face set 6 in the | | symmetry boundary patch | | | | SYMETRY | | | | is not in a strict plane, which means that at least one of its | | faces is not parallel to the others. To make the solver run | | you can do one of the following: | | | | (1) Make sure that this symmetry boundary patch is in a plane or | | axis by checking and regenerating the mesh. | | (2) If the symmetry boundary patch is an axis rather than a | | plane, change the tolerance of the degeneracy check by | | increasing the value of the Solver Expert Parameter | | 'degeneracy check tolerance' (the default value is 1.e-4). | | (3) Increase the value of the Solver Expert Parameter | | 'vector parallel tolerance' (the default value is 1 deg.). | | Note that the accuracy of the symmetry condition may decrease | | as the tolerance is increased. This is because the tolerance | | is the number of degrees that a mesh face normal is allowed | | to deviate from the average normal for the entire face set. |
