SPH outlet condition
Hello,
I am trying to se up a SPH outlet condition for my model. I am not interested in some particles so it would be useful to delete them while the run goes ahead and speed up the simulation time.
1) I have not found many references on this in HyperMesh. The previous threads on the community are not helping me much since they are for HyperCrash.
2) To create the surface that defines the outlet i create a new component where this surface is stored, do I have to assign the Card Image "Part" or <None> to this component? Which property and material should I assign to it in case I have to define it as "Part"?
3) How should I mesh this surface? How dense should be the mesh? In the Ditching example every surface segment has only one element. the example is not really explaining how to set up the SPH outlet condition. Is there a video for that?
4) I have two components meshed with SPH crushing with each other, should I create a SPH outlet for each component since only one part can be defined in /SPH/INOUT?
Thank you for your help!

You can create one in HM, from Solver Browser: Create --> ALE-CFD-SPH (it is incorrectly listed as SPH_INPUT though!)
The help has a section on what is required for Radioss
It depends on the specific use, but the surf can be meshed or defined as a plane
IIf you are creating as mesh, you should give it a part card image (or it won't be exported, you can give it prop ''VOID' I think)
