SURFACE MODELING OFCOMPUTER PANEL

Problem Description An instrument panel design was modified in a Case Study shown in

Section 3.

For this workshop add fillets to the corners of a surface for a

computer panel, remove the small tooling holes, and reduce thesize of the two openings on the right side of the panel for the

speaker plugs.

Create nodes and elements by meshing.

The geometry of the computer panel is shown on the following

slide.

tooling holes(eight total) replace

outer corners

General outline of the steps to be performed Import the STEP AP203 file computer_panel.step containing the

surface to be modified. Model units = 1.0 meter.

Follow the steps outlined in the case study Instrument Panel tocreate the fillets at the four outer corners of the panel, using fillet

radius 4 mm

Remove the small tooling holes that are in the middle of the panel(8 holes)

Remove the two circular openings on the right side of the panel andadd new ones with a radius of 2 mm

Mesh the part with the Paver mesher using Quad4 elements and anappropriate global edge length

Evaluate the quality of the mesh

After importing the parasolid surface, create the

corner fillets Geometry: Edit/Surface/Add Fillet

Enter 4.0 as the radius

Select the vertex, then the surface

Repeat the steps until all four fillets are created



7/10


Remove the desired holes and create 2 holes for the

speaker plugs Geometry: Edit/Surface/Remove Hole

Under Inner Loop Listselect all of the desired holes, the eight

tooling holes and the two holes for the speaker plugs

Select the trimmed surface

Illustrated above is the computer panel surface after all the

tooling holes and speaker plug holes have been removed.

Create the speaker plug holes using a smaller radius Geometry: Edit/Surface/Add Hole

Set the Optionto Center Point

Set Hole Radius to 2.0

Use Surface 1 for Surface

Use the following center points

[239 25 0] , [251 25 0]

Click on Apply

Mesh the model Elements: Create/Mesh/Surface

Set the Elem Shape, Mesher, and Topologyto Quad, Paver, and

Quad4, respectively

Enter an appropriate GEL for the model(around 2.5 or so)

Determine the quality of the elements Finite Elements: Verify/Quad/All
