How to apply pressure and displacment outside of the surface in LsDyna PrePost?

Altair Forum User

Hi, I am working  with LsDyna software. I need to apply: 1. pressure 2. displacement outside of solid part, on all of the surfaces in all directions? What is the best way to do this? So far I saw that most people determine curve of load t=f(F)  (I'll probably use it for applying pressure outside of my part), but I still don't know how to apply displacement. I am appreciate for any help

Hi anna_p,

If i'm not wrong, you mean how to apply imposed/enforced displacement to the surface. Right?

So, you can go to analysis page > Constraints > Change the load type to PSCRBDSP_N > select the nodes > tick the direction in which you want the displacement and enter the value (i.e. how much displacement you want to impose).

For example to impose 100 units of displacement in x direction follow below image.
