Hello ,

I have a worry, the model below represents the case of exceptional static loads  of a bogie  the model was made on Inspire, I wanted to know in fact on hypermesh which type of force I have to use because when I apply the force on one Node I have a very great constraint ,if I use the pressure I have a very small constraint. I used rigid elements also to bind nodes and apply the force to the master node but I do not know in all these assumptions which is the one correct. i 'am waiting for your help

regardly

    If you are using Solid Thinking Inspire for analysis & optimization.Then above screenshot loads shows that load acting on entire face not on single point.Connectors option allows you to use rigid elements (Rigid i.e RBE2 & Flexible i.e RBE3) for load transfer.

    Hello again ,
    I did what you advised me to do I chose elements rbe2 and I applied the force on the master node but in the visualization of the constraint I don't know why I do not see the constraint concetration In the surface where I selected the rigid elements, it represents a blue zone (0 constraint) while the other components are under stress ?? Normally the area where I applied my force must undergo more stress not ??

    Could you share screenshot of your model or .stmod file to crosscheck?you can use secure file transfer link to share your files.
