Problem regarding addforce

Dear All,

I am using “addforce” command for tensile deformation of a beam of 70 nm.
I have fixed the ends (5 nm each side) and rest of the body is mobile.
But when I use addforce, it streches the specimen in only one direction.
How to apply bi-directional tensile force using addforce command?

Without a few example lines from your input script,

who knows why it isn’t working as you expect?

Fix addforce lets you add force in different

components. You can verify for yourself it is happening

by dumping the force components.
