Disables boundary elements that have a surface stress error (Serr) greater than ten times the root mean square value (Rms) for all elements.
During matrix solution Map3D is attempting to progressively solve the simultaneous equations saved in the coefficient matrix along with any other equations describing the alternate material zones, fault-slip, creep etc. A converged solution is assumed to have been obtained when the maximum surface stress error and the maximum failure criterion error are reduced below the user specified stress tolerance STOL
In some problems, certain elements will not converge to a solution due to excessively poor numerical conditioning. If the user is satisfied the current level of accuracy, a solution can for forced by checking this option.
This function instructs Map3D to disable any elements with values of Serr > 10 Rms. A few iterations after executing this function, additional elements may appear with the same problem requiring this function to executed again. After a few times all elements will be disabled and the solution can proceed to convergence.
Extreme caution should be exercised when using this function as the results will contain numerical errors which could be significant.
Notes:
The distribution of surface stress error can be displayed by selecting
Plot > Surface Components > Serr Stress Error
from the solve toolbar.
The distribution of failure criterion error can be displayed by selecting
Plot > Surface Components > Ferr Failure Error
from the solve toolbar.
During analysis, the solve toolbar will be displayed when you suspend the analysis
only if the
has been checked.
