Hello everyone,
I'm trying to mesh a structure with complex partitions using mesh controls. When doing it on the user interface I'm first selecting all cells. In the following, I have to accept that the regions which are too complex for sweep meshing are removed from the current list of selected regions (see attached screenshot). So, this works fine.
For my python script I'm using the getByBoundingBox() Feature in order to select all cells. In the following it would be necessary to remove all regions which are too complex for meshing otherwise the script breaks with the following error message: Some regions cannot be Swept/Reolved.
Hi Carolin Bock ,
from my point of view it might be easier to seed one edge after another this might lead to better results.
You can try to use a code like that:
def seed_by_length(line_length, seed_number):
****p = mdb.models['Model-1'].parts['Part-1']
****edge_coord = [edge.pointOn for edge in p.edges if edge.getSize() ==line_length]
****if len(edge_coord) == 0:
********raise ValueError("Failed to find edge by length")
****for edge in edge_coord:
********p.seedEdgeByNumber(constraint=FINER, edges=p.edges.findAt(edge), number=seed_number)
Now you can seed all your edges of the same length in a controlled way by calling the function.
To seed by coordinates I would recommend:
def seed_geometry_edges(x, y, z, seed_number):
****p = mdb.models['Model-1'].parts['Part-1']
****edges = p.edges.findAt(((x, y, z),))
****p.seedEdgeByNumber(constraint=FINER, edges=edges, number=seed_number)
With these two functions you should now be able to mesh in a more controlled way. If you have multiple edge objects that you want to mesh in the same way you can easily concate them by using edges1 += edges2. I put them in the appended .py file for you.
If you are just looking for the code to do the same you are doing by hand, have a look at your .rec file or .jnl file, it should be hidden in one of those.
For more information about Abaqus Python I recommend having a look at: https://www.martinpletz.com/fe-scripting/
Please let us know here how it is working our for you.
Cheers,
Claus
P.S. The **** are just here to show the structure of the code.
