Midsurfaces created do not intersect each other. There seems to be a gap b/w the plates modeled that is equal to half the thickness of the plates. please help me with this. Since the model is large, i cannot individually use midsurface. kindly help with the same.
 
Hello!,
With FEMAP V11.1.0 the AUTOMATIC midsurface command has been improved a lot thanks to the new Parasolid techology: not only creates midsurfaces, but also compute intersections between midsurfaces, delete unnecessary parts and output automatically one component combining midsurfaces, the result is impressing!!.

When on, the pre-V11.1 Midsurface Method runs the three steps of semi-automatic midsurfacing (Generate, Inter­sect, and Cleanup below) at once instead of using the more advanced face pairing technique. Also, when using pre-V11.1 Midsurface Method, none of the other options are available.

When on, Combine Midsurfaces simply performs a Geometry, Surface, NonManifold Add on the newly created sur­faces in an attempt to create a general body, which usually aids when trying to create a mesh.

The Face Pairing Options can be used in an attempt to create a more accurate midsurface representation:

Combine Tangent Surfaces - collects all connected tangent faces, based on the Angle Tolerance specified, finds all faces opposite these faces, then creates a larger face pair set. By doing so, sheet metal parts and similar will mid-surface faster and more accurately with the additional connection information implied by the larger face pairing.

Reverse Face Pairs - simply reverses the two opposite faces or sets of faces in the face pairing algorithm. Turning on this option sometimes helps in achieving a better midsurface on complicated parts with a high level of curvature. If you are not satisfied with midsurface results, this option may help.

Best regards,
Blas.

so a relevent question ... what version of FeMap are you using ?

Hi ALL!!


Sorry i didnt mention the version, it is infact 11.1, but still the problem persists!!
I am attching some pics for the reference,

Thank you BlasMolero, this is exactly what i need but it is not working. Thanks in advance for the support mates
