Week 5 Challenge : Surface wrap on Automotive Assembly

AIM: To check the geometrical error and delete surfaces which are unwanted for surface wrap. After clearing geometry merge all 3 models and add the given target length of 3mm and perform surface wrap.

PROCEDURE :

• Surface wrap is basically used for meshing the components from outside if we wrap any component we can only see the outside components 
• In this model we are doing surface wrap for given model for outter side 
• Surface wrap is basically used to analysis to study the outside flow simulation or analysis the only require outter components. Surface wrap is used fpr the wrapping the component mesh the particular wrap accordingly by given suitable quality creteria 
• Firstly we need to remove all the unnecessary surface present outside the model because we should not have any holes or any dents in the model 
• we have engine, transmission and gear box to do topo cleanup for all the component separatly and do surface wrap individually and merge all the three components together and do surface wrap

here we deleted all unwanted surface and closed all the holes  in engine part so that it wont form any dents while surface wrapping 

here in this figure deleted all the unwanted surface for gearbox 

after deleting unwanted surface try to merge all 3 model together for that goto file > merge > select the model or file which need to be merged for the present model and click on ok

after merging all 3 model together goto mesh > elements > wrap > constant wrap > we can see constant octree on the screen click on it give a any name for that on castellation section check wether the wrap mode is in node out of structure  and property assignment must be in assign property from structure then click ok  and in mesh section give the target length of 3mm as per metioned above.

after that try deleting unwanted PID present on property by using compress option and delete them forcefully because its of no use 

select all the properties and shift it to other side and click ok then run the program it will nearly take 5 minites to wrap 

this is the obtained result and final model of surface wrap 

RESULT : delete the unwanted surface of ring like and ball like surface which are of no use 

we can try option PID and hide the main surface by not option to get all unwanted surface inside and outside the model try deleting unwanted surface, extra surface or overlapped surface for all three components for engine transmission and gear box and give the mesh length and do surface wrap
