Because I am currently working on a project that requires consideration of the nonlinearity of the material, which needs to come into contact with particles. However, after my research, Motionview has launched an OSFLEX flexible body function, which is currently a testing function and cannot be coupled to EDEM. Therefore, we can only rely on Optistruct to couple with EDEM. However, Optistruct is difficult to achieve complex movements because I can already use multi-body software from other companies to couple with EDEM to solve this problem. But I have not seen the coupling of MS-EDEM's FFLEX flexible body in Altair series software, so I would like to inquire about when this function will be developed, so that we can avoid using other companies' software lic
