This is why i have only modeled the bumper system and need to add a point mass to virtually include the mass of the vehicle. Without this, the impact would not be representative of an actual event due to inertial effects. <\/p>\n<p>I added a point mass in geometry and specific its mass and location but when i try to run the simulation i get the following error message: <\/p>\n<p>&quot;Invalid object (Point Mass) for an Explicit analysis. If the object is not visible, please disable Environment Filtering to review and remove\/suppress these objects from the Tree.&quot;<\/p>\n<p><\/p>\n<\/p>\n<p>I am surprised to see that explicit analysis does not support point mass? Is there a workaround? Same error is for distributed mass as well.
