3D Remeshing with Imported Point/Node Cloud Information

Altair Forum User

Hi,

Could anyone kindly explain to me how to build a model with point/node cloud information and then mesh it with Hypermesh please?

I have a model which was built and solved(standard displacement FE) in Abaqus and I am able to extract all element node position information out from the result file(.odb). What I would like to do now is to remesh this deformed geometry so that element distortions can be removed in order to be fed into a second analysis.

Since Abaqus remeshing ability is quite limited, I am hoping Hypermesh can help out.

Any suggestion on how this could possibly be done with Hypermesh? I am totally new to this software so any advice would be extremely helpful.

Thanks in advance.

Cheers,

Vince

Hi zhangws55

You can create mesh using point cloud data with a tcl script. Please refer to the link below.

The general method is :

import your points into HM
build new geometry from imported points by creating lines/arc/surfaces/volume...
make your new mesh with new geometry

Yes,

Please try the below script from the script exchange,

Using point cloud data it creates nodes, lines and hex mesh which gets dragged along the line

<?xml version="1.0" encoding="UTF-8"?>

And also shrink wrap will work provided you set the element size larger than the point cloud pitch.
