Objective: To perform a mesh for the IP Model under specified quality criteria by extracting midsurface and assign thickness

Methodology :

• Geometry cleanup.
• Mid- surface extractions of IP model
• Assigning PID.
• Automatic algorithm meshing by batch
• Assigning thickness

Procedure :

Perform topological and geometry cleanup

• Input the files component into ANSA
• Set the perimeter>length under Mesh module
• Give Topo for the entire component and check visually for any abnormal faces
• Errors can be rectify and corrected by the use of auto fix present in check up bar and also manually it can be done
• Check the geometry for error with Check Manager and correct the error like Triple cons, Cracked faces, Single cons
• After rectifying errors, rerun the geometry check up to make it is error free

MID –Surface extractions

• Measure the thickness of the features since plastic component have variable thickness
• Extractions of Midsurface involve offsetting each and every faces.
• Commands like faces>offset middle are extensively used even we can use skin casting
• Check for Geometrical errors again

Assigning relevant PID & Quality criteria

• Set PID for all the regions separately so that the Measurement of thickness can be done properly
• Use given quality criteria to mesh the component within the quality parameter
• Property assigned to RIBS and other features

MESHING – BATCH Mesh performed on IP model

• Batch meshing is a fully automated process, Automatically mesh multiple model files without human interaction.
• Select the Batch Mesh tool to open the Batch Mesh Manager window.
• Press the New button to create one of the following scenarios:
• Meshing Scenario
• Here the primary result is shown using batch mesh
• The appropriate result is achieved by splitting swapping and pasting the nodes
• Release the element and remove the unwanted cons and hot points
• After corrections, go to Quality criteria > presentations parameters> select the check box shell as solid

Conclusion:

1. The IP model geometry is cleaned up
2. The midsurface is extractions for entire part
3. Meshing is carried out for entire part with in quality at certain features to retain it
