MESHING HOOD FOR STRUCTURAL ANALYSIS

MESHING HOOD FOR STRUCTURAL ANALYSIS

OBJECTIVE:-

• To get rid of errors on Inner and Outer Panels of the hood.
• To perform a mid-surface extraction of the both.
• To build a Hem related to both panels.
• To mesh the model.

PROCEDURE:-

• The model was opened which was in .stp format which was automatically converted to ANSA readable format while importing.
• Ran a geometry check and corrected all the errors, if any.
• Isolated the inner panel and used the option Mid-Suface to get the mid-surface of the inner panel.

FIG 1:- Mid Surface of Inner Panel

• Corrected all the inner panel\'s errors, if present.
• Assigned a PID to the panel, with a thickness of 0.75 and also made a MID named Hood_Mild_Steel and assigned the MID to the panel.
• The similar procedure was used in case of Outer Panel.

FIG 2:-Mid Surface of Outer Panel

• Both the panels were shown where we projected the edge of the panels to perform a hemming process.
• After all the edges were projected, the outer regions of the outer and inner panels were deleted.
• The edge of the inner panel were pasted on the projected lines of the inner panel on the outer panel, to create triple cons, which was needed for hemming process.
• The hem area was isolated and was given a seperate PID under the name Hood_Hem.

FIG 3:- Hem Surface

• Later on the Inner panel, Outer panel and the Hem was meshed according to the given parameters:- Length = 5mm

FIG 4:- Required Parameters needed for meshing.

RESULT:-

FIG 5:- Meshed model as a result.

LEARNING OUTCOME:-

• Learnt to perform a mid-surface extraction of a model.
• Learnt the procedure of creating hems.

CONCLUSIONS:-

• Got rid of the topo errors of the entire model.
• Successfully created a hem.
• Surface Mesh was performed without any errors.
