[swash-users] Restrained floating object analysis with SWASH

[Agustin S. <agu...@gm...>]

Hello everyone,

I’m trying to model a floating object in SWASH using the *FLOAT*command. It
seems to work at first,  it reports the water level in the first iteration,
but then it starts showing *NaN* values in every subsequent step.

After I define the  INPGRID DRAFT /READINP DRAFT and run the model, the
PRINT file shows this:

* INPGRID DRAFT REG 323180. 5423030. 0. 818 750 5 5  *
* READINP DRAFT 1 'ShipDraft.float' 3 0*
* FLOAT 0.0, 1.0*
* ** Error            : Data field skipped:0.0
                                                  *
* ** Error            : Data field skipped:1.0  *


I can’t find the right solution. Has anyone experienced the same issue?
I’ve attached the code I’m using below
