The keypoint that you create must belong to a line, and that line belong to an area. Then mesh the area. This way ANSYS recognizes the keypoint as part of the geometry, and, as such, recognizes forces and constraints applied to that keypoint and is able transfer them to the mesh for FE...
Hello,
I want to obtain analytical solution to a beam loaded with simple bending at midspan. There is an equation, but it´s only valid for points located on the simetry line. I want to calculate deflection along the left edge. I know there is a displacement method that uses the stiffness...
Hello,
I´m running MATLAB optimization toolbox, and i´m using fmincon function for contrained non-linear minimization. I can run the code with no problems, but it only runs one iteration, and after it stop, saying this message...
Hello,
Try to issue the *vwrite command before /output. This should write the data you want into the file. Check ANSYS help for the sintax.

Hello Andrea,
Hello Niels
I suspect that you are not saving the results data you are trying to acess. before solving the model issue:
outres,all,all
Anyway,to get the displacement you should use:
*DIM command to issue a dimension for your array
*get command to get values on entities, (can be...
Hello Rich,
The way I would do it is to delete the area, then create keypoint and then several areas by keypoints, in a manner that the areas are created as you want the supports to be on. Let´s say you now have a rectangular area, which is the beam bottom area. You delete the area, create new...
Hello,
I´m not a bio engineer, so I will tell you what I know about the error. The error you are obtaining means there is something you need to improve. Usually this error happens when the local stresses on at least one element make the element distortion very high, and the analysis can´t...
Hello,
There are some differences between the analytical method and the FEM. The analytical method is a continuum and normally with stress equally distributed along the object. The FEM considers stress concentration, mainly considering the geometry. The stress concentration factor on ANSYS can...
I´m looking for the correct sintax of the *GET command, or any other command that can do what i´m looking for.

Hello,
I can select all nodes that I want.
NSEL,S,LOC,Z,-0.2
I want to get the maximum nodal z displacement in my node selection.
Can you tell me how? I tried to use the *GET command, but with no sucess.
I say the other thread, It could not help me either.

Hello,
I have selected all nodes with z coordinate equal to -0.2:
A=NSEL,S,LOC,Z,-0.2
I want to save the node numbers on a array, and then calculate the maximum Z displacement on the group of nodes.
Any help appreciated,
Regards,

Hello,
I want to know the name of the maximum z Displacement in APDL commands, and the total reaction force in the z direction, i.e, the sum of every reaction forces for the selected nodes. I know the displacement is UZ, but what about the maximum nodal displacement for the selected nodes? Is...
Hi,
If you go to the select menu, go to select entities, then choose areas. On areas, you have some options. Try the options one by one, and at least one should work! without the ANSYS code, It´s impossible for me to help any better.
I suggest you select areas by lines, or areas by keypoints...
Hello,
i´m doing a non-linear analysis, and I have hundreds of substeps. I can only list results for one substep at once. I want to choose for instance z displacement and list it for every substep at once. How can I list results for all substeps at once?
Thanks,

Hello,
First, i would list the keypoints, to see which number corresponds to the ones I would like to select. Then, I would copy the keypoint numbers to a text file. If you go to the select menu, then select entities, you can select keypoint by Num/Pick. You just have to input the keypoint...
