objective

for the given model ,check and dolve all geometrical errorsand asign the pid performing the meshing with suitable target length and quility criteria

target length for different part of model can be decided by own fine mesh will give good result

meshing wind tunel volume with tetra elent may take upto 2 days of times

so that is not compulsary tpo perform .as this is a majour project it is advise to mesh that completly by taking some day of time ,

procedure

first off all import the model

now this geometry looks as there is not proper connection was established .all over the geometry the red cons .so let hit toppo. for go to faces>toppo>box selection >hit middle mouse button

in the above geometry some red cons are visible . this is missing surface and fill surface

so clear all intersection error and clean geomtry

then assign pid all part

after we process of surface meshing let give universan quality criteria,let go quality parameter,skewness0.5,min length0.1 ,maxlength 6mm min target length =2mm,min target length=4 mm

creating wind tunel

go to toppo mode here the wind tunel is closed volume entity like room which is used for simulate the external flow analysis

length of car=x

front face of =4x

back face of=6x

top face of =3x

first we will calculate x value it is approxoimate we will take 6000mm

now we create the curve between these point

curve>create>slect the point will offset the face

we will do bottom face for target length 60 mm by given min and max length as 50 mm and 70 mm and top face pf 300 mm target length, and min max length 290 and 310 mm itds done go to pid manager>enable side face>go to paramer >spacing<manual spacing https://drive.google.com/file/d/14xA_LNE4gAdX4fiOHFt3NVkBIJdS-OhJ/view?usp=share_link
