Results Data in HyperMesh and HyperView
Results data can be post-processed using both HyperMesh and HyperView.
Developer
The Developer ribbon contains tools for automation and customization.
Plot Data in HyperMesh and HyperGraph
Plot data can be post-processed using both HyperMesh and HyperGraph.

        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.
