How to reflect the model with area connectors properly?

Recommended Posts

Hi, everyone.

    I encountered a problem when I reflected a model with area connectors. The model is symmetric, but the whole model must be analyzed in some cases.  I reflected the original half model (half model.hm) about xz plane of AxisSystem1 (ID=1) by using *duplicateentities and *reflectmarkwithoption and *equivalence commands, then merged the same components and load collectors. However, the analysis of the symmetry model (symmetry.hm ) cannot be executed properly and gives too much errors such as,

The errors in .out file reflect that the RBE3 elements in the reflected Glue component have wrong information. The RBE3 elements seem not to be reflected properly.

BTW, the half model can be analyzed normally.

I don't know where the problem is. Can anybody gives me some advices?

Thanks.

half model.hm

Symmetry.hm

Symmetry.out

Hi, @Q.Nguyen-Dai

    The half model (without reflection) works fine.

    The error state arises after reflection. 

     The original model without reflection and the reflected model are attached as "half model.hm" and "Symmetry.hm", respectively.

Thanks.

Hi, @tinh

Thank you very much for reply.

I used *duplicateentities command to duplicate elems, nodes and comps along with any attached loads, while the command *duplicatemark only duplicates the elems and nodes. Even so, I tried the "*duplicatemark elems 1 0" command to duplicate and reflect the elements, a lot of different errors about RBE3 data arises.

For the convenience of testing, I attached the duplication and reflection tcl file (symmetry.tcl). The "symmetry.hm" file can be obtained from "half model.hm" by using this tcl file.

Thanks.

Hi

Another way is to save half model as half.hm, reflect (not duplicate), and then import the file half.hm, and then equivalence

You dont need to duplicate and organize

Please try it
