Hello everyone, I hope everone is doing well. <\/p>\n
I have a question related to APDL in Ansys Mechanical. I have discover this langugage not so long ago and I launched myself into a project but I am facing strange problems. <\/p>\n
In my code, I use the *GET <\/strong>function to obtain the stress at some node (so far no problem), for example : However, where the nighmares begin, when I use the same function but for the node Node_2 = 18828 then I ran into problems : <\/p>\n Requested data is not stored for node 18828. Consequnelty, I checked the mesh I done in Ansys : Number of nodes<\/strong> = 81924. So I am node out of boundary. <\/p>\n I am also able to plot the stress at this point, so it exist. When I export the result (right click -> export) the result of the stress goes from node 141 to node 81924. MMmm ok I assumed, just where are the nodes 1 to 140 ? Anyway, my node is inside ! <\/p>\n In APDL when I use the function PRNSOL <\/strong>for the stress, I am able to see in the Post Output that nodes where found and assigned with a stres value. However, the number of the nodes goes from 1 to 11631, then switch to 81925 to 93555. This is wrong, and the worst is that the value of 1 equal the value of 81925, same thing until 11631 and 93555. Therefore, assuming that the script is looking here, then I understand that it does not find the node 18828, because it is skipt here (for marvelous reasons). <\/p>\n And also, because nothing make sens to me, when I plot the node ID min and max, I have, respectively, 1 and 163848 (?) where 163848 is two times 81924, why ? I don’t understand. <\/p>\n *GET,node_min,NODE,0,num,minD !Get the minimum node id<\/em> So all of this to say, that I would like just to have an APDL function to get the maximum principal stress (S,1) at one point who does not seems to exist, but it does. <\/p>\n PS : If needed I can send my code but it is nearly just what I am doing, getting values of stress at certain nodes. <\/p>\n Thanks you very much for your help ! \ud83d\ude00 <\/p>\n","protected":false},"template":"","class_list":["post-314278","topic","type-topic","status-closed","hentry","topic-tag-ansys-mechanical","topic-tag-ansys-mechanical-apdl","topic-tag-apdl","topic-tag-postprocessing"],"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
