Ideally, I would like to obtain the relationship between force and displacement, such that if I measure the displacement, I can derive the forces and moments acting on this structure at a given point.The result would be a matrix M, with F = M*x &#8212; F being a 6D vector with forces and moments along the xyz axes and x the 6D displacement.<\/p>\n<p><\/p>\n<p>For the first step, I did a static structural analysis with Ansys. I have some questions regarding the next steps,&nbsp;<\/p>\n<p><\/p>\n<p>1) Does Ansys already provide such a force\/moment-displacement relationship?<\/p>\n<p><\/p>\n<p>1) Can Ansys output the displacement in 6D instead of just x-y-z?<\/p>\n<p><\/p>\n<p>2) In theory, is the matrix I want to obtain the global stiffness matrix?<\/p>\n<p><\/p>\n<p>I am a bit stuck right now and would appreciate any kind of help or advice!
