Hello,
I want to simulate the flow through a 3-D domain by using ANSYS Fluent/CFX. The 3-D file is in stl format obtained through 3D-Slicer. I have used MeshMixer to make the 3-D file workable but i am not able to work with this file in ANSYS. Any suggestion is highly recommendable.
Thanks
Hi,
my suggestion is open it in solidWorks or inventor, and use the SW format, with the .part extension file, this format is easy to manage and fast and accurate to be imported into ansys.
Regards.
I rarely use commercial software, but highly recommend Tecplot. Do you know what form the STL file is? Binary? Text? It should be a simple matter to read the STL file and write out something useful like a PLT (ASCII text) for Tecplot or TB3 (also ASCII text) for TP2. If it's binary and you can't find the format, there are binary editors that will display single- or double-precision floating-point numbers.
Dear Vikas,
STL's files are always challenging for doing simulations... they are just points and connectivity rules for the triangles formed by them (more like a surface mesh). For the meshing tools that means that you have as many surfaces as triangles in the original STL, and many of them may be inverted, they can have intersections, etc. ANSYS has Spaceclaim now that can do your life much easier for dealing with those files. It has a module that can deal with STLs quite efficiently, you can repair, refine and remap STL's and connect them directly with Mechanical or Fluent. If you have a good STL import it in Spaceclaim and see if it does not complain too much (it has automatic tools to detect errors as well).
Kind regard,
Julian
If the file contains nodes (x,y,z) and elements (i,j,k,...) that's very portable and easily read by TP2 or Tecplot. Send me a link and I'll parse it for you.
I would like to thank everyone for their prompt help and effective suggestions. Your advice helps me a lot in solving my problem. I can now simulate the flow using on a 3D STL model. I have saved the STL file into part format through SolidWorks and after that, I have again opened that part file into SolidWorks and save it as a Parasolid format and then imported it in ANSYS Design Modeler.
Dudley J Benton Thank you sir for the help, Right now my problem is solved but i will like to take your suggestions in future regarding the STL file.
Marco Andrés Guevara-Luna Thanks Sir, it works for me.
J. Anaya Thanks Sir, I will try this one too.
Dudley J Benton Sir, after importing STL file to tecplot, can i convert it into ANSYS supported 3D format (.iges, .step, parasolid etc).
