© Advance Contech (Singapore) Pte. Ltd. Joint Created automatically when drawing frame or panel Must be turned on (show) for snapping Turned off (uncheck “show”) to save some rendering time Max joint = 131,070 Check “invisible” to tidy up screen (it is still “showing”!) 22

© 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
