Week 5 Challenge : Surface wrap on Automotive Assembly

AIM:

To learn about surface wrapping around an assembly, which is surface meshing along the entire volume. For the given model we need to do topo clean up and merge all the 3 components and then perform meshing

Target length = 3mm

INTRODUCTION:

Surface wrap is the process of meshing where the designer is only interested in the outside surface of the assembly i.e., the component inside the volume will be kept as it is. This kind of meshing is only used for the simulation in which we are interested in the outer surface only like external flow simulations

MODEL:

• ENGINE:

As we can see there are many rings like surface which don’t look like of any use as this ring are used by designer sometime to create fillets in the model so we need to delete all those surfaces which don’t have any significance Now, in wrap meshing the interior part is not that important so we don’t need to worry about all the single cons or all the overlap surfaces but it is good practice to delete all the unwanted surfaces so make the geometry as fine as we can

MODEL:

For the above model we need to start with deleting the rings on every fillet

An easy way to so look at all the rings quickly we can use NOT Option with PID selection and we can hide the important parts by which we can see all the rings clearly and then we can carefully delete the unwanted surfaces

• TRANSMISSION:

We don’t need to worry about the internal surface but on external surface we need to close the holes and make it even

• GEARBOX

Similarly, we need to do topo clean-up and close all the openings

After completing merge i have to create meshing by the help of the element tool where a option called wrap.

Here we are going to put the target length

this is the final one.

CONCLUSION:

We learned to merge the geometry and then we created the surface wrap mesh
