Caedium CFD Simulation: Air Flow Through a Pipe into a Box

This screencast shows how to use Caedium Professional to create the geometry and simulate a steady-state turbulent CFD simulation of air flow through a pipe into a box. Also you will see how to create velocity vectors and particle tracks within the flow volume and monitor residuals as the simulation converges. The screencast is based on the "Pipe into a Box" and "Incompressible Flow Through a Pipe into a Box" tutorials at http://www.symscape.com/

@bassefa1984 Caedium supports hexahedra (mapped) and tetrahedra (unstructured) meshing with precise sizing function controls.

Turbulence models include Spalart-Allmaras, Standard k-epsilon, Realizable k-epsilon, k-omega SST and others. For full details visit the Symscape website and check out the Caedium RANS Flow add-on.

Yes, Caedium can perform unsteady time simulations.

how do you approach grid meshing?

what turbulence models does it offer?

can u perform transient sims?

@DanFrederiksen The end goal is to have a water-tight volume, but there are various ways to achieve this. If you have the option I suggest using STEP (.stp) as the exchange format - it preserves volumes and tolerances better than IGES (.igs). If you have individual NURBS surfaces then you can try using Volumes->Stitch to form a volume and then subtract that volume from a larger box (volume). When complete you want the volume to represent your fluid around your object.

rather stiff geometry creation and manipulation but workable for this limited application. pretty decent video tutorial but it skips a very vital part, how to bring in designs for aerodynamic testing.. you really should have a tutorial on that.

I've imported my mesh object from another cad but it seems your program only deals with 'volumes'. how do I make it into a volume and is it even possible with what was separate nurbs surfaces?
