'Static, General' Vs. 'Static, Riks' load step
'Static, General' Vs. 'Static, Riks' load step
(OP)
Can someone please outline the difference between the 'static, general' and 'static, Riks' loading method. As I understand it, general takes the load and breaks it into increment applying each one on the result of the previous increment whereas Riks computes the difference between the increments and then adds this to the previous increment however I'm struggling to grasp this.
Any help appreciated.

Tom

Riks is best suited to problems where there is unstable buckling or collapse - it uses an arc-length method to determine the response of the loaded structure, where there are siginificant changes in the structure's stiffness.
