Problem with DynamicMesh: nozzle moving along wall
4 Attachment(s)
Good morning everyone
I have a problem with dynamic mesh I hope some one can help me figure it out I created a geometry of a nozzle filling water into some rectangular space using SALOME, two volumes (nozzle, box) > Partition > create groups > Meshing > create group on geometry, and they are connected with a surface called (internalFace) I run the case in interFoam and it is OK I try to make the nozzle move in the Y direction while dumping the water in the volume and the code crashes at specific time. What happen is that the cells in both volumes stay connected while the nozzle is moving, so they get to a very high aspect ratio and Co number jumps very high. I think I miss one more file other than the dynamicMeshDict - this is the only file I used to move the nozzle and using interDyMFoam. Attachment 55410 Attachment 55411 Attachment 55412 Attachment 55413 This is the main folder of my simulation and also a screen shot of the mesh at a slice showing the nozzle (Top) and the space (bottom) Can someone please figure out what I am missing? Do I miss a file called pointMotionU? Code:

Looking for a tutorial on Inkjet printing

Hi everyone
Can someone please give me a tutorial on Inkjet printing? If not available, can I get a help in this problem? I am modeling the geometry in the pictures. Simply, and inlet nozzle into some domain, fixed inlet flow rate and the nozzle has a linear motion during the simulation. I am using interDyMFoam, dynamic mesh. Now, I created the geometry in salome, made a COMPOUND of the cylinder and the box. There is an interface inbetween, called InternalFace. I try to create a baffle for this interface, AIM, and use the dynamicMeshDict to move the nozzle zone. simulation always crash and I cannt figure out the mistake. I attached the relevant files, 0/U o/alpha.water dynamicMeshDict system-folder Regards |
