Week 4 Challenge : CFD Meshing for BMW car

OBJECTIVE

MODEL FILE LINK ADVANCE MEHING ON CAR MODEL

ERFORM THE CAD CLEANUP OF THE CAR MODEL AND ADVACE MESHING

the car model should be free of any error

write a detailed report explaning how you cleaned the model in ANSA step-by step with snapsshots for each step.

1.INCREASE THE RESULATION

we will have do a resulation to caputure the geometry error .

mesh deck>perimeter>length1

2.HIDE THE PART WHICH ARE NOT SYMETRICAL

by hide the ppart which are not symetrical so that we can do the geometrical cleanup only for one half and reduce the process of geometry cleanup

3.CUT THE GEOMETRY INTO TWO HAVELS

toppo deck>faces>plane cut

select any 3 points of the diresction which we want to cut the planned middle click

4. check the one half which is having more errors

by clicking the ctrl+shift we can she in which half there was more no of errors

5. REMOVING ONE SIDE WHICH IS HAVING MORE NO OF ERROR

BY SELECTING THE ALL FACES ON THE LEFT HAND SIDE

WE CAN GO UNIVERSAL DELETE

CHECH GEOMERIC ERROR

REMOVE THE INTERSECTION ERROR

REMOVE THE ALL INTERSECTION ERROR

CREATE A ANOTHER HALF OFF THE PART

we have clared thegeomtry error for one half and mirror that geomtry create the another part

use 3 point curve

utility transform>symmetry>mirror3>pount apply will given the mirror face of the body

clean radioter overlapping

now wind tunnel creation from the point face of the the car will have a create a relative point with a distance 3*1

use curves or line for the botton surface offset the bottom face and create the top face of the wind tunel

BEFORE MESHING MESH PARAMETR DIALOGUE BOX THE TARGET LENGTH HAS BEEN ENTERED AFTER SELECTING GENERAL CRIETRIA AND MESH TYPE HAS BEEN SELECTED TRIA
