Plate Radius

Team,

 

This may sound like a silly question does FEMAP have a simple way to add a radius at the corner of a plate? 

I know it can do it with a solid but I have a mid-surfaced model that I want to add an interior radius. 

 

Thanks

 

John

Dear John,

Not possible to fillet a NonManifold body (ie, a General Body Add) directly, not command exist to do it.

I have tried to reproduce your problem, creating a General Body Add based in two bodies using default tolerance: in the top window the two bodies, and in the bottom window the result after performing command GEOMETRY > SURFACE > NonManifold-Add of the two bodies:

If I perform GEOMETRY > SOLID > FILLET I get the following error:

Solid Fillet
2 Curve(s) Selected...
Fillet/Chamfer Failed.Check continuity of selected edges or possible overlap with other geometry.

The "trick" is to issue commands GEOMETRY > SOLID > CleanUP (this way you are free of cuts)

following SURFACE > RECOVER MANIFOLD GEOMETRY and you have the body prepared to perform a GEOMETRY > SOLID > FILLET like the following picture:

But not need to "explode" the full General Body Add, simply issue command GEOMETRY > SURFACE > EXTRACT and select the three surface of the corner, next clean using GEOMETRY > SOLID > CleanUP and you are ready to perform GEOMETRY > SOLID > FILLET command.

In any way, finally perform a GEOMETRY > SURFACE > NonManifold-Add command to join all surfaces in a General Body Add.

Another trick could be to create just the detailed geometry of the fillet in a separate surface body and ...

perform the NonManifold-Add command ...

and finally clean the internal curve imprints using MESHING TOOLBOX > FEATURE REMOVAL > CURVES > COMBINE SURFACES.

But in fact, despite the many options we have to reach the desired target geometry, not a direct command exist to work with GENERAL BODY ADD geometry, many limitations, please FEMAP guys we need it, thanks!.

Blas.

Blas,

 

Thank you for all of your help!

You are a wonderful resource to all of us in the FEMAP forum.

I do hope the FEMAP team updates the non-manifold add and general body add, can be confusing.

 

Thanks, 

 

John

A pleassure to be of help!.

General Body Add and NonManifold-Add is exactly the same term, one is the geometry body and the other the name of the command to create it, see the folowing image. When you have a "T-Join" like geometry think this is a General Body Add geometry, and to create it you needto use command GEOMETRY > SURFACE > NonManifold-Add, OK?.

Parasolid do not support this type of "T-Joint" geometry, this entity is created thanks by FEMAP developpers, they are pushing hard the limits of Parasolid team!!
