Good Morning, we have some problem using STWAVE v. 6.0.17 [built: (2012-3-19 12:00) OPTIONS: (REAL32, opt )]. We re-installed our SMS 11.0.5 on PC with Windows 7 Home edition 32 bit and now, every STWAVE simulation finished immediately, without creating output file, or creating output files with WAVE or PERIOD value with a range bad. For example with a simulation with this spectra with "propagation only" mode: - ANGLE ( meteorologic) : 135 °N - Hs: 1 m - Tp: 10 s - gamma : 3.3 - nn: 4 - gauge depth:100 m but in the grid cell output value for depth near 100 m I have: -Hs: 9 m - Direction
