Dear OpenSEES Community members
Can anyone tell me the meaning of the following parameters, which are defined in "ndMaterial" source code,
What does these variables CommittedStrain, CommittedStress and commitState represents??
Thanks and regards

the prupose of 1 analysis step is to find the next converged stp, given the current converged step. In the nonlinear analysis the model usually will go through a number of trial steps. these are not on the solution path, but trial solution points. If the convergence test is satisfied at a given trial step, the analysis step stops. before it returns, it tells the model that this is a converged step and hence the need for the 2 methods. if no converged step is found and the analysis fails, the revertTo LastCommit methods are invoked.
