Is there a way to select the elements touching another plan. I was planning to solve the above problem by defining a plan instead of path. Thanks in advance

I select elements based on Path command in APDL. I take a specified path and select the elements crossing that path but due to initial imperfection I am not able to do so.

Thank you Rick for your reply, Yes I am using UPGEOM Command (initial imperfection). Since the selection of items is needed in the postprocessing so to select item in preprocessing will not be a good option that is why I was searching if there is some command which will give me the shape of...

I am using ANSYS APDL for the analysis. I want to select some elements from the model after doing my analysis but due to deformation of the model the elements location change and are not selected by suitable commands. If somebody could help me in getting the pre-analysis geometry that will be...

OK I got your point thank you for the reply

I need the load deflection curve, the time steps itself represent load. I am using time history plot for the load deflection curve

I have the load vs time relation I want to plot the graph between the two. the number of nodes is around 1700 I don't know which node to select for the curve. your advice will be highly appreciated. thank you

I use load control. the curve is shown below: https://files.engineering.com/getfile.aspx?folder=5b02c843-990e-4ab1-93d9-02c3bea39002&file=Load_def.PNG

I also did the modal analysis to check whether the boundary conditions are good. the results were consistent. The first mode shape is attached below

I am Using ANSYS APDL. I am doing non linear analysis and the first buckling mode is used as initial imperfection (using a scaling factor). The settings are like this: 1) Large deformations on. 2) time at the end of load step 1000 3) automatic time stepping on. 4) Number of substeps 100. 5)...

I am doing non linear analysis of girders and the same is not converging it is showing error after 37th sub step. please recommend some remedies.

The last line in the code "*SET,TSF,YSF *(1+FS), ! TRUE STRESS OF FLANGE (error)" is showing not a valid command and I have run this command singly to execute. the error is like this" no longer a valid command charcater - please use !*SET,TSF,YSF*(1+FS),! TRUE STRESS OF FLANGE please answer

Thank you sir, It worked

(1)I use NUMMRG,ALL command in ANSYS APDL and when I run Modal analysis its showing the areas are not glued together. Does NUMMRG,ALL command glues together all the surfaces. I am attaching the MACRO below. (2) And the last line in the code "*SET,TSF,YSF *(1+FS), ! TRUE STRESS OF FLANGE...

Ok thank you

Thank you Erik for your suggestion. Will try it

sorry rb1957 I am using ANSYS APDL, From post-processing I have the options of plotting the curve between node displacement and time. But I need a curve between displacement and load. By the way who told u I was shouting at you.

HOW TO PLOT LOAD DEFLECTION CURVE.

ITS SHOWING BI-LINEAR CURVE BUT I THINK IT SHOULD HAVE A DESCENDING LIMB. THE ULTIMATE LOAD IS AS EXPECTED. THE CURVE IS ATTACHED BELOWhttps://files.engineering.com/getfile.aspx?folder=bd99d495-fcd3-4361-80f5-d2d49136b16b&file=CURVE.PNG

HELLO, I HAVE DONE THE NON LINEAR BUCKLING ANALYSIS OF A BEAM. WHEN I PLOT LOAD - DEFLECTION CURVE ITS SHOWING A LINEAR GRAPH WHICH SHOULD NOT BE SO. PLEASE SUGGEST ME HOW CAN I GET THE NON LINEAR PLOT.
