As per standard procedure, here is the project link.
This is less of a project issue as of more a mix of getting things correct.
So some background, this project is two fold, to deduce the average wind velocity on a specific floor in the building of interest and to also deduce the Turbulent Kinetic Energy just outside the interested region of the building of interest. With reference to the Greenmark reference document for ideal simulation characteristics, specific requirements for a “proper” result are given.
While I’ve kind of figured out a large part of the things I need to do (thanks everyone who helped along the way), input of the wind log function (page 101 of the document) and the meshing characteristics I want are still issues.
The wind log function or rather the inbound vertical wind profile is described here but a simplified version that I want to use is stated in page 101 of the reference document. The question is how do i input such a profile? On top of this, if my desired absolute velocity is 2, again how do I input this value into the boundary conditions?
Second problem, so far I’m aware that in order to allow for some sort of ground effects to be included into the simulation, I’ve referenced the validation case for “Wind loads on buildings” in the Simscale Validation documentation. There they have two important sets of mesh refinement I’m unfamiliar with. One the bounding box layer refinement to produce a fine mesh from the bottom which gradually increases in size as height increases. Two, the inflation of the boundary layer. How do I use those meshing refinements optimally and in particular, is there a way to calculate out the values to input into the parameters of both meshing refinements?
Additionally, if you are interested in the geometry I’m trying to mesh, refer to “Full Geometry 1”.
Thanks for the help! I hope you don’t mind the long read!
