Can we mesh a component with hex elements by using batch mesher tool? If so, could you please suggest me how to do?

    Hi Bhavana,

     

    Currently there are some limitations in generating HEX mesh through batch mesher, Though tet mesh can be generated with batch mesher (refer to the tutorial HM-3140)

    We do not do any hexmeshing in batchmesher, however if you want to just use Batchmesher GUI for multiple parts with a custom tcl script doing hex mesh, you can do that.

     

    So with some simplifications it is possible to hex mesh - 

     

    1) you can do that for simple models with solid map,

    2) use hex-core meshing,

    3) shrink-wrapper with hex mesh, etc., if it satisfies your requirements.

     

    Regarding batchmesh setup, it will be similar to  bm_housing.tcl.

     

    If you have a script which works only on geometry, you can setup batchmesher jobs with criteria and param files which skip geometry and meshing operations, giving you almost the same geometry as you imported. 

     

    Or you can use tria meshing, as in tetrameshing script, and then in post meshing use custom script mentioned above to do the hex mesher based on your meshed model. Shrink wrap might be the easiest to do hex mesh.
