Explicit Bathe implements an explicit algorithm by KJ Bathe that has improved numerical damping for high frequencies. ExplicitDifferenceStatic is an explicit integrator intended for static relaxation pseudo-static analysis. Motions are damped out using a Local Non-Viscous Damping method, inspired in FLAC.
ref PR #1694: LagrangeMP_FE - remove wrong check
Adding set/updateParameter to ElasticMultilinear
ExplicitBathe -> Like ExplicitDifference but with improved numerical damping that can be controlled with parameter p. ExplicitDifferenceStatic -> Meant for (pseudo) static analysis with explicit dynamics. A controllable local non-viscous damping force is added to remove dynamics. This is better than viscous damping because it converges faster and does not bias the static solution in the presence of plasticity. This is inspired in the methodolocy used by FLAC for static analysis based on explicit integration methods.

Two independent bugs in the original material: 1. revertToLastCommit produces wrong stress when creep is active. Root cause: after a rejected step the integrator calls revertToLastStep, which re-evaluates the material at the previous committed time. The unconditional iterationInStep++ at the end of setTrialStrain consumed the first-iteration slot during that re-evaluation, so the subsequent redo saw iterationInStep >= 1 and skipped recomputing creep, committing a stale (zero) creep strain instead of the correct value. Fix: reset iterationInStep = 0 in the same-time branch (committed-time re-evaluations are not part of a new step) and move the increment inside the new-time branch so it counts only genuine new-step iterations. The iterationInStep < 1 gate and the optimization it provides are preserved: creep is constant across Newton iterations because it depends only on committed history and elapsed time, not on the current trial strain, so computing it once per step is correct. 2. sendSelf/recvSelf crashes for any creep setting. Root cause: FEM_ObjectBrokerAllClasses::getNewUniaxialMaterial has no case for MAT_TAG_CreepShrinkageACI209 (tag 236), so object reconstruction from a saved stream returns null and segfaults. Fix: add the missing include and switch case. Also corrects the data Vector size from 27 to the actual 22 scalar fields serialized. Changed files: SRC/material/uniaxial/CreepShrinkageACI209.cpp SRC/actor/objectBroker/FEM_ObjectBrokerAllClasses.cpp
