midas Fea 2013 v1.1 release note

  1. 1. A d v a n c e d N o n l i n e a r a n d D e t a i l A n a l y s i s S y s t e mRelease NoteRelease Date : May, 2013 / Product Version : FEA 2013 (v1.1)1-1.

  2. 2. 2 / 7Enhancementmidas FEA 1. Pre Processing1-1. Improvement in data import from midas Civil and midas Gen Data import using mct and mgt file Cross-sections data that are not supported in midas FEA are imported as user-type. Cable elements are imported as truss elements.Previous version: Nodes and elements are only supported for the import from midas Civil or midas Gen.FEA 2013 (v1.1): Properties, boundary conditions, loads and analysis data are additionally supported.File > Import > midas MxTCivilFEACivilFEA
  3. 3. 3 / 7Enhancementmidas FEA1-2. Improvement in ‘Frame to Solid’ and ‘Frame to Plate’ functions This function converts frame in midas Civil to solid / plate elements in midas FEA.Previous version: Only one continuous straight line can be converted at a time.FEA 2013 (v1.1): More than one straight line can be converted at the same time.Geometry > Frame -> Solid, Frame -> PlateFrame modelin CivilPlate modelIn FEAFrame modelin CivilPlate modelIn FEA1. Pre Processing
  4. 4. 4 / 7Enhancementmidas FEA1-3. Creating tendon profiles by entering 3D coordinates This new input method creates tendon profiles of spline or round type in the 3D space by entering 3D coordinates.The curve types (Spline, Round) which are frequently used in the tendon modeling provides the user with the easier wayto create tendon profiles than previous version.Geometry > Curve > Create 3D > Tendon ProfileSpline or Round typeTendon coordinatesSymmetric copy androtation of tendonfor convenient tendonmodeling1. Pre Processing
  5. 5. 5 / 7Enhancementmidas FEA1-4. Improvement in mesh quality of Hexa-Dominant Mesh The algorithm of generating hexa-dominant mesh is improved to create mesh with high quality.Compared to the mesh consisting of tetrahedron only, hexa-dominant mesh in midas FEA providesmore efficient and better analysis results using much smaller number of elements.1.

  6. 6. 6 / 7Enhancementmidas FEA2-1. Generating graphs from nonlinear static analysis results Generate graphs about the relationship of load & displacement and stress & strain for the nonlinear static analysis. It is possible to draw graphs using the results from different analysis cases.This feature enables the user to generate graphs easily without the use of MS Excel.Select node or elementwith a relevant component.Post > Nonlinear Static Analysis > Nonlinear Static Result GraphsSelect a graph type.2. Post Processing
  7. 7. 7 / 7Enhancementmidas FEA 2. Post Processing2-2. Update geometry of analysis model using buckling mode shapeCreate a new model file in which the geometry of analysis model is revised based on the mode shape of linear buckling analysis. The new model can be usedfor geometric and material nonlinear analysis to find a buckling load considering geometric imperfection.Geometric imperfection can easily be included in the analysis model. The buckling behavior of the model can be furtherinvestigated by performing geometric and material nonlinear analysis.Post > Linear Buckling Analysis > Update Model with Imperfections Select a buckling mode to revise thegeometry of model.Buckling mode shapeNew analysis model in which nodalcoordinates are updated based on theselected buckling mode shape andscale factor.
