<p>Hello, I would like to insert an “ANSYS Commands” script under the  “Solution” tree in Mechanical that finds the stress at a specified node, and then inserts that value into a parameter that I can use to minimize the radius of a fillet (another parameter) to keep the stress under a certain value.  I have searched all over, but haven’t been able to find the answer.  I know I have to use something like:<\/p><p>*GET, vm_max, NODE, 151, S, EQV<\/p><p>But I get a message in Solution Information that says “Requested data is not stored for noded 151”.  I definitely have Von Mises stress specified as an output for plotting.<\/p><p>Also, I assume I have to create an output parameter first, but in the Parameters block in Workbench, the field “new output parameter” is greyed out.<\/p><p>Thank you!<\/p><\/p>\n","protected":false},"template":"","class_list":["post-423751","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
