I am trying to model a wedge. I use symmetry for front and back of my model but when I want to use symmetry for the right part of my model I cant do It.
in fact I model the wedge in half and use symmetry for the half but in this situation my model doesnt move. thanks for your help. |

What are you simulating with the wedge? What do you mean it doesn't move? You will have to be more clear.

hi evcelica
I want to investigate on interaction between fluid and structure. I uploaded my files and put their links here. something is wrong but I can't find it. http://www.mediafire.com/watch/38pj2j6lwxwe49h/CFX.wmv http://www.mediafire.com/download/ko...gdb/FSI(2).rar thanks |

I am trying to define some monitor points on one of the side of the wedge to record pressure.
first I assume my body is rigid and I did it. its link is here(movie). for doing this first I need to define my points exactly on my rigid body(?) and then the points should move with my rigid body(?). another time I tried to do the simulation with the assumption that my body can has deformation( Hydroelastic). but this time the problem is bigger and as I said something is wrong and I can't find it. I put it's files here(the rar file). thanks. |

totally :
1 - how can I define some monitor points exactly on my rigid body? 2 - how can I set the points to move with my rigid body? (some monitor points that move with rigid body) 3 - please see my rar file(FSI) and say its problem to me. the file is for a hydroelastic simulation. thanks. |

You can try to create a new coordinate frames related to the rigid body then define the monitor points in this new coordinate frames.

Hi Abou ali
1 - when I want to define a monitor point there is an option (position update frequency) and I can set it on Every time step or Initial Mesh Only. what's the option for? 2 - If I create a new coordinate frames related to the rigid body and set my monitor points based on the new coordinate frame then will my monitor points move with my rigid body? thanks. |
