Problem with Glue boolean-operation

[gemas]

Hi,

I'm currently trying to define a simple 2-D geometry consiting of
different rectangular areas. When I try to glue them by aglue,all command (or modelling>operate>boolean>glue>areas) I keep getting this error:

The input areas do not meet the conditions required for the aglu operation. No new entities were created. The AOVLAP operation is a possible alternative.

and I can't figure why. I tried the overlap operation (aovlap) but I don't get the separation I want. Here's my simple code:
/PREP7
et,1,plane121
mp,perx,1,80
rectng,0,200,0,200
rectng,20,30,200,125
rectng,20,30,0,75
rectng,0,20,200,125
rectng,0,20,0,75
rectng,30,200,200,125
rectng,30,200,0,75
rectng,20,30,75,125
aglue,all

and you'll find the print-screen of my geometry attached.

Thanks for your help !!

try this......

/PREP7
et,1,plane121
mp,perx,1,80
rectng,0,200,0,200
rectng,20,30,200,125
rectng,20,30,0,75
rectng,0,20,200,125
rectng,0,20,0,75
rectng,30,200,200,125
rectng,30,200,0,75
rectng,20,30,75,125
nummrg,kp,,0.01

Hi,

unfortunetly I still get that message:"The input areas do not meet the conditions required for the aglu operation. No new entities were created. The AOVLAP operation is a possible alternative" even with nummrg,kp,,0.01.

 

[PriamEngineering]

you don't need the aglue if you do as above. the nummrg will do the gluing for you. all areas will be joined... don't believe me? try this. copy and paste into ansys excluding the nummrg. See the double lines? now put in the nummrg... dada...

/PREP7
et,1,plane121

Hi Priam,

thanks for your help ! Actually, I'm a beginner and I'm trying to reproduce a problem in order to train. I'm not able to differenciate the two areas acting has my load, in the post-processing, even if I apply the loads on the line. To make my self clear, I would like to get picture_1 (here attached) and I get picture_2...How can I keep the lines of the rectangulars in red and blue in my final result ?

Thanks for your help, very appreciated !

Sorry, wrong attachement !! picture_2 is what I want and here's picture 1, what I have !!

Your using AnsysED! you are not allowed to post course work questions here. Sorry.

Hi Priam, no, this is not a course work, I'm a graduate electrical engineer, and I'm currently doing a master thesis in research (without any course). I need to simulate the electrical potential behaviour of a certain electrode configuration I'm using. Because I have never used Ansys before, I'm simply trying to get the same results as published in a paper, as a ''self-training''.

If my problem is obvious to you, can you please help me ?
