MARC-1353 Title: Failed elements are not deactivated in PFA Product: Marc

Siebel CR: 1-285939129

Fixed in Release: Marc - 2011 Description ( External ): The number of layers of a shell element with regular material should be odd due to the integration procedure (Simpson's rule). This is automatically enforced in the code, but was accidentally also done for composite materials. The extra layer usually did no harm, but for progressive failure analysis with element deactivation it had the effect that elements were never deactivated if the number of layers were even. Elements are deactivated when all layers have failed, but the erroneous extra layer would never fail since it was not active.

MARC-1349 Title: If element type 47.48.144.166.169 (rebar) are used standalone. large disp is wrong Product: Marc

Siebel CR: 1-285979711 Fixed in Release: Marc - 2011 Description ( External ): If element types 47,48,144,166,169 (all rebar elements) would be used stand-alone in a model without being embedded in their regular counterpart elements the results for LARGE DISP and LARGE STRAIN would be wrong.

SOIL), materials which were not defined via the model definition option SOIL did not get the region type NO FLUID PHASE.

MARC-1313 Title: Incorrect post file for magneto/struct job with Maxwell Stress Tensor Lorentz Force calculation Product: Marc

Siebel CR: 1-286654571 Fixed in Release: Marc - 2011 Description ( External ): In a coupled magnetostatic-structural analysis the Lorentz force was only written to the postfile when the Maxwell Stress Tensor method was used. Since this method is chosen in a loadcase the postfile did not contain this force in increment zero. Also when for some loadcases the Virtual Work Method method was used the vector would be missing for these loadcase increments. Now the vector is always written when requested irrespective of the method being used. By default, however, this vector is not written, since only the summation of this force over a body has a physical meaning.

In a parallel DDM analysis using the Multifrontal Sparse Direct Solver (solver 8) results could deviate from the results obtained for the same job in a serial run. The deviations can be reduced by using a tighter tolerance on the SOLVER input (e.g. 1.0E-6). On platforms where the Pardiso (solver 11) or the MUMPS (solver 12) solver are available it is recommended to use to these solvers instead. They often are faster than solver 8 and don't show the deviations when comparing results from parallel and serial runs.

Siebel CR: 1-287501480 Fixed in Release: Marc - 2011 Description ( External ): Mentat wrote the same convergence criteria values for either relative or absolute creep testing. The default auto creep tolerances on creep strain change and stress change were also inconsistent with the ones documented in volume C when the absolute testing option was used.
