Week 3 Challenge : CFD meshing on Turbocharger

AIM- perform volumetric mesh on the given model with given target length.

OBJECTIVE-

1-topology cleanp of the given model of turbocharger

2-perform surface mesh using target length given for different part .

3-perform volumetric mesh using tetra cfd

BODY-

Steps to be followed-1 open the given model in ANSA using File>open

2-enable labels of given icons in ANSA window by right clock on bottom and tick show labels

3-Go for geometry check by following step  tools>checks>geometry

tick all except unmeshed  and  click on exicute

4-created surface where single cons are present in the model

 GO   topo>faces>new

select any in    existing surface/coon/fitted

selest cons where surface is to be created >middle click    

alterante option go TOPO>cons>fill hole>select cons>middle click

6-repeat step 5 to fill all holes or surface where surface is absent or single cons are present

7-repeat step 3 now there is no error except the needed triple cons 

8-swich into mesh mode  MESH>classic Mesh

change view fom EXT to PID

9-go     LISTS>Properties 

10-right click>new>PSHELL>PSHELL

enter name and ok

11-repeat step 10 and create all part's PIDs as shown below

12-apply these PIDs to respective parts of the model

right click on a particilar PID>show only

right click again on same PID>apply

 enable PID or PID region>select shown model part by box selection>middle click

 

image of model after creating all PIDs is shown below

GO properties>right click any of PID>show only

set target length go  classic mesh>Perimeters>length

for MACROS and PERIMETER  one by one

select model by box selection >middle click>set target length as given in question

GO  mesh generation>spot mesh>box selection of bse surface and middle lick

meshed part is given below

go-volumetric mesh>define

delete 4 outer shell PID and rest are as shown above

select each PID by right click>remesh

meshed part is shown below
