Creating model in Ansys
Creating model in Ansys
(OP)
Hi,
I have created bar model of the retractable roof
made of steel in autocad, and I would like to export it
to Ansys. I would like to model airflow and calculate
wind pressure coeficients on the structure.
Questions:
- which is the easier way, import dwg to solidworks,
create iges, import to ansys, then create areas
and volumes, or create 3d solid in Solidworks and
after that export to Ansys. Or maybe exist other
way to creating?
- I will use flotran modul of Ansys, but I don´t
have practical examples of using this modul.
Where can I found some.
Thnx,
Robert

RE: Creating model in Ansys
-import the swg into Solidworks
-create the solid model
-optional export the model into a Parasolid file type
-open Workbench to attach the active geometry (Solidworks must be opened) with all the advantages of this procedure (see the documentation) or import the Parasolid file and do the analysis; if the analysis can't be done into Workbench, export to file to Ansys.
This is just my option.
Instead of Flotran, take a look at CFX,
RE: Creating model in Ansys
I have tried it on the prism with using parasolid file.
Now I must deeper study Flotran, or CFD
to model my aim.
With this import Ansys automatically chose
an element type, or I must define it?
Now im going to create a space around the prism.
I saw some tutorials in the program, but
they didn´t have economical printable version
(less usage of paper). Is it possible to download
on the web, or export somehow these tutorials.
Thanks,
Robert

Regarding the documentation, for the printed version you must pay for it, as far I know at least for me.
RE: Creating model in Ansys
I have found some Ansys tutorials.
Good luck.

RE: Creating model in Ansys
I solved this tutorial, but there are some
differences.
http:/
First of all, the geometry of the boundary is given
unsymmetrically in this tutorial on the axis of the car, not as is shown in the figure.
The car isn´t situated on the bottom of the boundary
as in the real life on the street. The values of these
tests could be comparisable with the real situacion.
The final velocity plot of air depends on the distances X, Y from the boundary, and don´t depend on Z?
On the final plot there are velocities 6 times
bigger as the starting velocity of air 24.6m/s.
How is it possible?
Thank You so much,
Robert
