Framework to plug certification methods to assess margin of safety from the model and result information.
PhysicsAI
Use PhysicsAI to build fast predictive models from CAE data. PhysicsAI can be trained on data with any physics or remeshing and without design variables.
Results Data
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data
HyperGraph is a data analysis and plotting tool with interfaces to many file formats.

        To specify and evaluate road excitation, COSIN/road uses one central subroutine evrmr (COSIN environmental models: road main routine).
        Road Profiles and Obstacles in COSIN/io Format
        If COSIN/road detects the road file in COSIN/io format, it first tries to read certain information common to all road types within this format (see Data Common to all COSIN/io Style Road Types).
        Road Profiles and Obstacles in TeimOrbit Format
        If COSIN/road recognizes the road data file is in TeimOrbit format (typically, the file name extension is rdf), it branches into the respective reading and evaluation routines.

TeimOrbit 2D Road Type: ramp

If the ROAD_TYPE is set to ramp, COSIN/road searches and reads the following data items in the [PARAMETERS] section:


Name of input variable	Unit	Meaning
`height`	length	Height of ramp.
`start`	length	Start of ramp (travel distance).
`slope`	length	Slope of ramp; 1 means 45 degree.
