2D Mesh Boolean

Roshan Shiveshwar · May 2020

Hello All,

I want to perform 2D mesh union operation of two set of overlapping elements. Below are the images for reference.

Here, both mesh A and B consist of 2nd order tria elems. Mesh A is from an older FE model built in different pre-processsor (Abaqus CAE) and Mesh B was generated within HM. The objective is to preserve mesh-A and stitch the extra mesh region present in the mesh B to it.

I have tried using the mesh Boolean operation, but did not get any solution. Not sure if I am missing out something.

So, is there a way to achieve this ? I am open to tcl scripting as well.

Thanks,

Roshan

The operation can be done manually.

Manual operation is fine for simple examples like the one stated above. But, for a real models it becomes very tedious and time-consuming (too many faces to deal with). Hence, looking for a direct option like mesh-boolean
