Since midas FEA provides analysis results in Works Tree in a tree structure format, it is very easy and convenient to check various result data. midas FEA provides various Visualization functions to effectively check analysis results in the post-processing mode. Iso-sufrace Plot displays surfaces, which represent the results of equal magnitudes. Results above or below a specified level are produced. Slice Plot displays results at sections specified by the user. Clipping Plot displays results of one side from a plane specified by the user. This feature is very useful for checking analysis results for tunnel interiors in conjunction with advancing excavation. Partition Plot allows us to mouse-drag and separate individual element groups. The element groups can be individually translated, rotated and scaled (magnified or reduced) so that we can check the results in a separated state. This feature is very useful for checking analysis results in a model. Using Diagram Plot, force and moment distribution diagrams for beams and trusses can be produced in various graphic types and values. Stress fields in stress analysis, velocity fields in flow analysis, etc. can be checked in vectors. The size of vectors (variable, fixed or user defined), method of expressing arrows, color process, etc. can be freely selected by the user. midas FEA enables the user to readily extract various analysis results. Some examples are: change of results by transient analysis at a specific location, change of results for different locations in a specific time, etc. midas FEA provides contemporary techniques of simple mouse-operated manipulations to display Legend. The band of legend including max/min values, colors for the band, size, location, etc. can be manipulated.
