© Advance Contech (Singapore) Pte. Ltd. Mesh 8-node quadrilateral shell element for slab and wall Meshed from panel (4-nodes), remember to assign (and check) properties and loadings Converted into 8-node elements Solver input file is being generated Super Element is being formed Manually Converted back to 4-node element Upon return to Pre-processing mode (Optional) To avoid converting meshes back into 4-node element if there is a super-element defined in the model 25

© Advance Contech (Singapore) Pte. Ltd. Mesher (Frame) Divide frame(s) to establish continuity with meshes/frames Properties and loadings are inherited by new frames 27

© Advance Contech (Singapore) Pte. Ltd. Mesher (Panel) Two type Generic mesher (by NTU) Regular grid (only for 4-edge panel) 28

© Advance Contech (Singapore) Pte. Ltd. Meshing : (could be) an iterative process To reduce number of elements 1. Purge all meshes 2. Convert all panel back to 4-node 3. Mesh Panels 4. Re-mesh Panels (  for some cases) 5. Mesh Frames For existing model with meshes 29

© Advance Contech (Singapore) Pte. Ltd. Purge orphan joint(s) Orphan joint : generated during iterative meshing process Solver doesn’t accept model with orphan joint! Select any one orphan joint, click {Delete}, all will be purged 30
