API Changes — Woo 1.0+rev4127-git-6bcabce documentation
https://www.woodem.org/api.html
Woo 10 rev4127-git-6bcabce documentation. Woo keeps track of current API version in. Which is set from the internal woo.apiversion. Every script should state the API it was programmed for by setting. Or (1,1,77) which is converted 10000*1 100*1 77. Functions which changed their behavior in significant ways (other than fixing bugs) will issue a warning about possibly unexpected result. In that case, this page can be consulted to find out about was to update the code accordingly. A related change is that.

Woo 10 rev4127-git-6bcabce documentation. Woo has a built-in 3d view made for detailed inspection of simulations and seeing what matters. It supportes displacement and rotation scaling, selecting and inspecting objects and many other things. These are force chains during the cylindrical triaxial test, with scaled (magnified) nodal displacements:. With configurable coloring, length and export to VTK if needed:. This is the average flow for the screed wall of which video is shown below:. Rarr; Woo modules.

Woo 10 rev4127-git-6bcabce documentation. DEM usually assumes simplified geometry (such as spheres) and the actual physics must be expressed by the contact model. We take care to document contact models. Thoroughly and implement them carefully. Was developed under a contract, and the source code. Is not all that complex). Large family of models based on Hertz theory. For non-adhesive contact) adding adhesion. This is an ancient screenshot, when still running under Yade. The pellet contact model. Was deve...

Woo 10 rev4127-git-6bcabce documentation. The rolling screen is used for sieving of granular material. The simulation was evaluating not mass rates and PSD for each individual section of the screen. Improvements of the screen design were validated using batch of simulations with several varying parameters. This video is a HQ rendering of the screen being filled (via POV-Ray; set the video to 1440HD for better quality):. This is a detail on the gap:. This screen had several decks and complex transitions:.

Woo 10 rev4127-git-6bcabce documentation. There are many shapes supported by the Woo engine. Minkowski sum of 0-D simplex (plus) with sphere;. Minkowski sum of 1-D simplex (segment) with sphere;. Minkowski sum of 2-D simplex (triangle) with sphere;. Often useful as boundary conditions). These shapes are uni-nodal (they have all their mass and intertia lumped into a single node). Besides them, there is support for multi-nodal particles (. And uses the conrete contact model. Pharma capsules are generated by.
