A few testers have discovered a dll conflict when trying to open the new 5.0 beta version of HEC-RAS. The following message appears:
This happens if you’ve installed the HDF5 Viewer as described in the new “Combined 1D and 2D Modeling with HEC-RAS” document on page 115.
HDF5 is a new file format used by HEC-RAS to store 2D output as well as some 1D output (in addition to the standard output files and dss files). The HDF5 file contains more output information than is currently available in the HEC-RAS graphics and tables, such as velocity information for cell faces and face points. The HDF5 Viewer is currently the only way for users to access the 2D velocity output.
The issue is resolved by uninstalling the HDF5 Viewer. HEC will be posting an updated install soon that corrects this problem.
