2D Mesh Boolean

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.

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

Hi,

perhaps mesh imprint functionality can be utilized.

Thanks Simon.

Mesh imprint seems to work. I think with tcl scripting I can use mesh imprint to perform the 'union' operation.
