Creating Point Mass in Explicit Dynamics

      Hey!

      I was wondering if it's possible to create a point mass in explicit dynamics (to shorten my simulation times)?

      I created a remote point but when I click on geometry, the point mass option cannot be selected. The only option I can select is surface coating.

      Any help is greatly appreciated!

      Thank you

      Hi Shajee,


        You should be able to insert a point mass directly by right-clicking on the geometry:



      What version are you using, I just tried this in 19.2

      Hi Sandeep
      I'm using 18.2, I can see the point mass option, I just can't click it for some reason. The button is suppressed. Do you think that it is a software issue?

      Hi Shajee,


        I think it might have been introduced in 19. I just checked in 19.1 as well, if possible please upgrade?

      Hi, guys!


      I want to do an impact simulation in ANSYS using Explicit Dynamics. When I remotely attached a point mass to the body surface, I encountered with an error: "Deformable behavior for remote entities is not supported in Explicit Dynamics systems. Please change such behavior to Rigid". But when i changed the point mass behavior to Rigid, another error occurred: "Could not transfer loads and constraints to the solver". What is wrong here? How do i do a simulation in Explicit Dynamics with a remotely attached point mass to body surface. Thanks in advance!
