GfsWave in spherical coordinate system
|
| |
Hi all Gerris experts,
I have recently browsed through wave.c and can not see the function metric_sources as in river.c. So I would like to know whether the spectral wave model GfsWave can be used in spherical coordinate system.
Best regards,
Liang Wang

open_memstream.c for Solaris
|
| |
Dear All
I am installing Gerris version 130112 on an M9000 Solaris 10.
I get this message when trying to compile gerris :
"open_memstream.c", line 32: #error: Sorry, not ported to your platform yet
cc: acomp failed for open_memstream.c
What is a way around this problem or is there an adapted version of open_memstream.c... more »

high order interpolation in gerris
|
| |
Daniel & Stephane,
have you done any work on high order interpolation in gerris ?
People have tried local splines in two dimensions

culverts and pipe networks
|
| |
Hi Stephane,
Two weeks or so ago I sent a patch for the culvert module. Did you manage to receive it?
On another topic of drainage modelling: How feasible do you think it is to help me implement the SWMM interface for Gerris?
See the general SWMM page here:

Coding issues wrt gfsriver and gfsourcepipe
|
| |
Hi all,
I have developed an improved testcase for the culvert module. This has led
me to the following 2 issues which i would appreciate comment on:
1) in river.h the gfssourcepipe structure is defined, which makes use of
the h1 and h2 variables. My understanding is that these variables represent... more »

Gfsriver bed and free surface boundary conditions
|
| |
Good day gerris experts,
Thermal powerplant outfall eia's typically need to quantify the difference
in temperature between the ambient environment and that of the discharged
effluent within say 100m of the outfall. To model this problem it is
necessary to impose a zero heat flux boundary condition at the bed and some... more »

about thermocapillary flow
|
| |
Hi, Stephane and all
I plane to develop the branch of thermocapillary flow into Gerris, in which the surface tension depends on the temperature that the Marangoni effect drives the flow.
The equations are obtained that a tangential component of surface tension due to temperature... more »

Gfsriver variable wind drag
|
| |
Good day gerris experts,
I have recently browsed through river.c and can see that there has been a
lot of development in terms of resolving the vertical structure of shallow
water bodies.
I would like to know whether it is possible to implement the wind drag such
that it is dependent on time, magnitude and direction. This will allow... more »

configure.ac
|

Hello. I noticed in the NEWS file of Automake
[link]
that (lines 172--174):
- Future versions of Automake will likely drop support for the
long-deprecated 'configure.in' name for the Autoconf input file.
You are advised to use the recommended name 'configure.ac' instead.... more »

gfs_interpolate_from_corners
|
| |
Hi Stephane
I was looking at the interpolation function and there is something I
do not quite understand. After getting the corner values, you
interpolate the values within the cell using the corner values AND the
value at the center of the cell. This gives an interpolation function
which looks a little bit weird in some points inside the cell.... more »
