Can someone tell me how to transfer geomatry from Pro/E to GAMBIT with out using STEP file.

You can try IGES format but I found STEP is better because it exported my 3D volume as a real geometry whereas IGES made it virtual (in Gambit).

Does your license file contain gambit-pro e connection??

Hi!
Importing file to gambit by using STEP function is definitelly better. If you use iges file import you are going to have problems with virtual geometry and you will also have to clean up the geometry (double lines, not connected lines...) - like in one of the Gambits tutorial. Regards MATEUS |

Mateus: can you give me more information and if possible this licence file to me.

I was under the impression that when you did a proe direct import to gambit all it did was automatically create and import the step file?

You might try a vrml file as the intermediate file format.

A vrml file uses faceted surfaces though so if you take through curved surfaces you wont get the same geometry in Gambit as in ProE

Hi,
The easiest and the most robust option is for importing a model from Pro-e into gambit is direct cad import. However, this option requires a special licence key at additional cost . The second and probably the most common option is to use step file. It is more robust than iges file but you should use the correct step format because Proe has two different formats for step files while gambit supports only one of them. I do not suggest you to use any of facet geometry formats because resulting geometry may not allow you to use several modelling tools in Gambit such as boolean operations. I suggest you to follow these steps: 1) Defeature your model in proe: Get rid of any unnecessary geometric details (such as fillets with small radius, holes, screw paths etc...) in Pro-e by deleting or supressing the relevant feature. 2) Create your flow domain: If your Pro-e part does not represent your flow domain(for example, you have a pipe geometry but actually need void in the pipe for CFD simulation). 3)Check your geometry in wireframe mode to determine sliver faces or bad edges.Especially in the vicinity of fillet intersections. Try to fix them in proe 4) Export your model using step file. 5) Import it into Gambit and check the geometry. If there is a bad faces or edges that might not been noticed in proe , turn to proe ant try to fix them, too. If they dont appear in proe model(That means they are results of translation process) you will have to fix them in gambit and I strongly recommend you to USE virtual geometry option. Regards |

but does the direct Cad input not just automate the STEP file creation, import and deleting of the temporary STEP file. T
he original question was how to bring in ProE data without using STEP. My understanding is that the ProE direct import is mot actually an import of native ProE geometry but an import of STEP geometry. |

Hi Phil,
Actually, direct cad option is not an automated procedure for step import. As I know, direct cad import converts proe based gaometry to ACIS based goemtry without using any auxilary file such as STEP or IGES. Direct import works between cad kernels not file formats. Why I explained Step option although the original question emphasize `without step` is that Patel might encounter some model accuracy problems if he used step option before and my suggestions was intended for eleminating possibility of geometric corruption during the process.

I stand corrected, just checked out gambit myself. do you know if this a feature of the latest version or has it always been acvailable? Phil |

Hi Phil,
As I know,Gambit-ProE integration is available for version 2.0 and later. There is only step or iges import options for free in old versions. For an extra charge, you can use some third party tranlators from spatial engineering and marchetti engineering (spelling may be diffrenet you can check it in gambit user manual- FAQ sections) Regards |

I agree gelislim what he said.Usually you used pro/e direct interface into gambit, the geometry was became "virtual " , that means you can't use boolean operation.In my point, created the flow range in pro\e, then exported to gambit by step is a good way.
