to perform the fatigue analysis presents some numerical singularity making the equivalent stresses reach high values in some small zones.&lt;br&gt;My idea was to write a MAPDL code that rrecognises the values over a certain tress that are effected by the singularity and overwrites the solution in the database with realistic values resulting from a linear interpolation of the resulting stresses in the zones wich do not present this singularity.&lt;br&gt;The problem is:&lt;br&gt;&lt;br&gt;the code works fine, and it assigns the correct values to the critical nodes, but now I need to display the udated results in the ansys mechanical tree and launche the fatigue analysis with the updated data and I don&#8217;t know how to do that specifically.&lt;br&gt;Is there a MAPDL command that updates the results shown in the tree or is there a way to export the updated stress results and use them to perform a fatigue analysis in a separate workbench analisys?&lt;br&gt;&lt;br&gt;Thanks to anyone who will
