Hi All,

Has anyone here been successful in defining the *DEFINE_SPH_INJECTION card? I have been trying for a couple of days now and can't seem to get it to work. I am trying to continuously feed SPH particles for a dam-break wave. What I have tried is defining a new part ID for the generated SPH particles, a node set of the SPH particles where I want the injection plane to be located, defined a local coordinate system, initial velocity, and area. However, whenever I set the Begin Time to start at zero seconds it crashes at the initialization but when I set it to one second it runs the model but no SPH particles are actually created. Has anyone successfully used this card and can tell me how to define it properly or provide an example?

I attached the keyword file in case you want to look at the model.

Thanks!

@csuznxg not luck getting the SPH_INJECTION card to work. I ended up not using it but I will be circling around back to this problem in the near future as I still need to figure out how to use that card.

@pjayI made it, but I have some not understand about the AREA terms in *DEFINE_SPH_INJECTION card. I don't know what the correlation between AREA and the area of node set.
