Dear reader,
When we design structures for wind action/loading, pressure/force coefficients are required.
Design code provides values, for common building shapes, but for unusual building shapes, it's hard to say if they are the right ones.
And most clients don't pay for wind tunnel study.
ANSYS fluid dynamics/fluid flow (CFD/CFX) module has the ability to perform this type of analysis similar to a wind tunnel simulation.
By using workbench and importing from autocad:
- the external surface (shape) of building,
- or simplified building shape as solid,
a 3D model can be done in matter of minutes.
Although I think analysis would take a few days.
So if you have an example/tutorial in Ansys of simple building shape and a comparison between analysis values and design code pressure coefficients please share it.
If it's in workbench, modeled with graphical interface it will be highly appreciated.
Thank you.
