Mesh Breps - Mesh Resolution

Hello everyone,

i am trying to figure out, how exactly the mesh resolution works for rectangular shapes.

Let’s take the example of a rectangle with set geometry (x = 5 m and y = 5.1) and a MRes set to 2.5 m.

How does the mesh resolution split the uneven y-size of 5.1?

Thank you!

The mesh resolution simply creates triangles with approximates edge lengths given by the Mesh Resolution input. Please see 3.9.1: Mesh Breps - Karamba3D 2.2.0

Hey Matthew,

thank you very much for your quick response! I think I partially understood the mesh resolution.

But i should have been a little more specific about my example and thus my question.

I am currently working on a parametric model that consists of different slabs and walls. I have designed these as separate meshes for later assignment of loads and other boundary conditions. I have manually ensured that the mesh size is identical so that the nodes at the connection match. However, this only works if the dimensions are a multiple of the selected mesh size.

Hence the question of what happens if the dimensions do not match, see illustration.

In Case all surfaces were meshed, the surfaces would be connected via the common nodes, but it would no longer be possible to assign anything to individual components (slabs and walls).

Following up, i have a question about the relationship between the mesh and the surface loads in the exact mesh load const. Via Karamba 3D Chapter 3.2.1: The mesh where the load is applied and the underlying structure do not need to be connected. It needs to be fed into the “Mesh”-input-plug.

Does this mean that the mesh of the surface and the load must match or in case of differences, will the load be assigned the closest surface nodes?

Thank you very much!

Kind Regards
Patryk

Hi, if you need the slab and wall to be connected you can identify the specific input points for integrating into both meshes for the meshing process.

Thank you!

I’m sorry to ask so much, but at which point do i do this?

The slab receives the input MRes as distance and the wall as number of quads in a direction both in the form of (V: … F: …) in a list.
Later on, i transfer the separate meshes (V: … F: …) in the mesh to shell component and lastly combine everything in the element component of karamba 3d.
