Does NUMMRG,ALL command in ANSYS APDL Glues all the surfaces together

Does NUMMRG,ALL command in ANSYS APDL Glues all the surfaces together

Does NUMMRG,ALL command in ANSYS APDL Glues all the surfaces together

(OP)
(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 (error)" is showing not a valid command and I have run this command singly to execute.
please answer

RE: Does NUMMRG,ALL command in ANSYS APDL Glues all the surfaces together

I would post your questions in the Ansys forum.

I would perhaps suggest to use Workbench (WB) because you have been doing this for weeks, and this could be done in minutes in workbench - APDL has a very steep learning curve. WB is using APDL in the background so it is the same just that the GUI is much easier to use (one can say that WB is another pre/post processor for APDL). In WB/DM one can make everything parametric anyhow.

As for this: I told you before to use APTN and then together with NUMMRG,ALL. So remove that part (ASBL,...) and use this


CODE --> apdl

L, 200, 202
L, 201, 203
APTN,ALL
NUMMRG,ALL
DFLNG = 7850 ! DENSITY OF FLANGE & STIFFNER MATERIAL 

For the mesh use ESIZE,0.01, and AMESH,ALL

Thank you sir,
It worked

RE: Does NUMMRG,ALL command in ANSYS APDL Glues all the surfaces together

No worries - good that it is working

RE: Does NUMMRG,ALL command in ANSYS APDL Glues all the surfaces together

(OP)
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
