hai im new to ansys ls-dyna, im doing a fyp on rollover test. i watch a video on how to do it. so i have 3 geometry, the platform that rotate i apply as rigid and also goes for the surface of contact. The prototype i apply as flexible because i only want the deformation of the prototype. when i apply boundary condition. Rigid body angular velocity on the platform. it does not tilt. so i had to trial and error. for starting i just have the tilting platform in the analysis and from what i discovered is when my geometry is in rigid state it does not move (i apply all kind of force, velocity) it still wont move. but when i apply the platform as flexible it move. then i went back to put the prototype on the tilting platform, it does not move again. when i suppress the prototype, the platform tilts. i seem to have no idea what to do now. please help, if you may, can someone help me guide to do the simple rollover test with a short running time. thank you in advance guys.
