Dynamic Solution Type using IMFLAG in *CONTROL_IMPLICIT_GENERAL

There are two classical solution methods available in LS-DYNA to solve a given problem. The widely popular “Explicitâ€? solution scheme, using the central-difference method, is applied to short-duration transient dynamic problems while the “Implicitâ€? solution scheme is used for static problems. Both of these methods have their advantages and disadvantages which depend entirely on the…

Sometimes even minor model changes can introduce stability issues indicating a lack of robustness. Runs that die prematurely squander significant resources, something which I generally refer to as “simulation wasteâ€?. A recently developed procedure that…
