University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr. 3 -4, Slide 2 Topics Covered ADCIRC modifications East coast tidal database (EC2013) Grid improvements Bottom friction options Run parameters Results West coast tidal database Grid development

University of Oklahoma - School of Civil Engineering and Environmental Science ADCIRC Workshop - Apr. 3 -4, Slide 3 Version Modifications Problem: Global harmonic output memory issue –problem with large grids, numerous constituents too many constituents and stations – led to problems initializing the arrays for the elevation and velocities present on several computing architectures – TACC, OSCER, ERDC Solution: changed from global to local output – harmonic and hotstart use command line options –M write local files for harmonics –S write local hotstart files –R read local hotstart files adcpost required to develop the global fort.5* files
