Pre-processing using ANSA - Tool test-1

Objective:

To create mid surface mesh for the given sheetmetal and plastic component

Part-1:automotive plastic component- switch panel

geometry:orientation and geometry errors are cleared

midsurface:midsurface is extracted manually using ofset, middle option nad srufaces are patched using extend option.

midsurface mesh:

properties created and assigned:

thickness assigned to features as shown

Part-2:BIW sheetmetal component

geometry: orientation adn geometry errors corrected.

midsurface extration: since the component has uniform thickness faces offset is used to create midsurface.alternatively aut midsurface->skin can also be used.

preparing midsurface for meshing:

since the component is nearly symmetric, symmetric faces are deleted to save meshing time.

meshing: remaining faces are meshed

transform->symmetry optionm is used to completed the model.and elements/geometries are patched.

Assigning thickness:PSHELL property is created and assigned to midsurface.
