gluing areas ansys

[Arturo79]

Hello everyone, with reference to the attached figure, how can I "glue" areas a1,a2,a3? aovlap and aglue controls do not work.
thanks for any answers and good evening.

partition area (aptn)
aovlap works if areas are complanaries
aglue only works if the areas are adjacent.

hello, first of all thank you for the answer.
I tried to do as you suggested but it gives me this error message:
"topological degeneracy detected for aptn command. try modifying geometry slightly or loosening
the tolerance (btol command). if btol is relaxed, be sure to change the tolerance back to the default after operation."
I tried to change that tolerance value but nothing. .

probably the areas are close but do not touch.
Alternatively you can create a "line to surface" contact of "bonded" type

the problem according to me is that the height of area 1 is less than that of areas 2,3 and therefore the contour does not intersect completely.
In fact, if the dimensions of the three areas are equal, the command works well and the areas are glued.

Unfortunately the problem I have is more complex (this is just an example) and I would not like to get to use the contact elements.
However I also tried to intersect the two areas, making the area 3 longer, but it doesn't even work.

 

[Arturo79]

I have to find the solution without using the contact elements.
observing geometry, the various commands cannot work because it is impossible to create other entities from areas 1 and 2 as area 3 does not divide each area into two or more parts.
I need to find some artifice using mpc or hard points without significantly altering the model.
I thought there was some dedicated command I didn't know, though if I find some solution to the illusion.
Good evening! !

You caught me in chestnut. the options I have indicated do not work with the old solid modeling kernel of ansys. You should engage in a series of operations on a little long and boring areas... for example move the working plane on each area and then use it to divide other areas. once they are all divided, that is, that they touch only with the edges (lines) you can make an aglue.

hi, in the end I solved the following: instead of "drawing" the central reinforcement (area a3), I designed a "c" turned upside down having the area a3. once the division of the areas (aptn), I deleted the two areas of the "c" that I don't need. is a bit laborious but at least avoided contacts and non-linear solutions.
Hello and thank you! !
