The heading from __init__.py says:
so I think that i use a right version.

Good... obj['bevelToResMap'] is a python dictionary, which maps a string (str(round(e.bevel_weight*100))) to an integer. The integer tells how many cells you have requested on edge "e". For book-keeping, I use the Blender native edge feature "bevel_weight". For this reason it is important that the user does not manually edit edge's properties (floats bevel_weight and crease are used, as well as boolean use_edge_sharp). I do not know what happened in this particular case, but you should be able to reset bevel_weight by selecting all your block structure and forcing 0 cells on all edges. 0 cells means disabling forced edge resolution. If you do want to force some edges, you'll have to repeat that procedure.

Let me know if you get through.

Thanks a lot,
Your explanation lit my brain up ;)
Now, at least I can correct my errors.

Thanks for you input, Bruno. I'll have a look at it! Good git usage is not one of my strengths :-)

There was a bug in the new insert smoother feature, which was revealed when objects were scaled. Should be fixed now.

quarter cylinder
 

P { margin-bottom: 0.21cm; } Hello Kalle,


P { margin-bottom: 0.21cm; }
I am trying to learn to use swiftBlock and based on your cylinder example, I would like to create a quarter cylinder. I am attaching the created blender file.

P { margin-bottom: 0.21cm; }
When generating the blockMeshDict, the « fetching edge's polyLines from Circle » step is not considered. I guess this is due to the fact that, for a quarter cylinder, the Circle object is not closed. Is there a solution ? :eek:

P { margin-bottom: 0.21cm; }
Thanks in advance for your help.

I see... I took the freedom to adjust your model somewhat...

Thank you very much Kall,
I test your new blender file ;)

There seems to be errors during the generation of the blockMeshDict. The blockMeshDict, and log.swiftblock remain empty ... :confused:
I use Blender 2.62. Do you have the same problem?
cheers

Please use 2.66 and the latest swiftblock, as I used that for saving the blend file.

K

Ok, sorry ... :p

Thank you so much! ;)

Hi! I have some problems with the installation of the addons.

I have downloaded blender 2.66 and also the SwiftBlock .py documents. I've compressed all of them in a .zip. Then, in blender, in userpreferences addons I selected install from file and I select the .zip I've created before. I think this extracts the .py files in the folder - /home/$user/.config/blender/$version/scripts/addons. Still, is not working.

Does anybody have the same problem?

Hi,

I've never tried such an installation procedure. I always simply do like I wrote on the wiki

K

I just pushed a new SwiftBlock to the repo. Now there is a button which, when clicked, allows you to delete internal patch faces and add missing patch faces to your block structure. Internal patches is merely an aesthetic problem, but it can be nice to clean them anyway. External patch faces is on the other hand tedious to create, which is also reflected in the pipe bend example, where I just left them out. Now they can be created with just a few clicks. I have not changed the old pipe bend example at the wiki, so you can try it on that case.

p.s. there were some issues with book keeping of (forced) edge resolution and grading, which meant that you could effectively set a few different gradings. Now should be able to have up to 100 individual grading/resolution settings.

Swiftblock Aid
 

Hey all

I am interested in using swiftblock to help me create a mesh for flow over a bump. But sadly I am a blender noob (and openfoam). So far I can only import a stl that I created in solidworks. How can I go about learning swiftblock.

Thnx for your time

Hi,

I would recommend first to get familiar with blender. They have a lot of good stuff on their website. You can also find good info on youtube. You'll have to be able to do some mesh editing.

Then, I'd advice you to read the page on openfoamwiki, and download the examples there to get an idea of the concept.

Good luck, and get back here if you run into trouble.

K

Thankyou for reply

I have been looking into the things you have mentioned, especially examples such as pipeblock and quarter cylinder.

With my bump profile (pretty much a cross section of an airfoil) it is quite defined, and my question is is this type of structure applicable to swiftblock. I have attached an image.

Thankyou in advance

Sure, that is easily done with just one single block.

I guess you run this problem in 2D. If so, remember that OpenFOAM still needs a 3D mesh, but only one cell in the non-solved-for direction, and "empty" as boundary type for patches normal to that direction.

K

Sorry for the bad picture but it is a 3D structure.
I will be working on it over the next week. One thing I am struggling with is the select edges option, and when I hit preview the warning that preview mesh is empty to few vertices selected or broken block structue/ or cannot find object for edges . Sorry for all the noob like questions but my supervisor and I are interested in the swiftblock add-on and can see loads of potential.

I see. I looks like you have enabled swiftblock for the blender object that actually carries the geometry. You have to have two separate blender objects. One object carries the block structure, and the other object (the one from your CAD software) carries the mesh that will be used to construct the block's edges... I know this is a little confusing, but I had to implement it this way to get a working addon.

If you open the "structural part" example, you can see that there are two blender objects present, and that the object carrying the block structure has ticked the "set edges" and the name of the object carrying the geometry is given there.

You should not click "enable swiftblock" on the geometry object.
