open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello Everyone,
I am new in TELEMAC.I am trying to simulate a submerged breakwater during wave pass.First i make a triangular submerged breakwater for simple test.However it seems that SISYPHE take the triangular submerged breakwater as topography.How can I fixed the submerged breakwater in the flume bottom ?
Attachment file is the triangular submerged breakwater and case file.

Thank you in advance!

It's hard to tell without the geometry file. Also what do you mean by Sisyphe takes the breakwater as topography, isn't that what you want? Or you want to have different grainsize on the location of the breakwater?

thank you for your reply.i forgot to put my geometry file.
Attachment is my geometry file.Please have a look.

thanks alot!!

Option 1:
in noerod.f, replace:
CALL OV('X=Y+C ', X=ZR, Y=ZF, C=-100.D0, DIM1=NPOIN)
by
if (ABS(X-1.5))<0.1) THEN
CALL OV('X=Y+C ', X=ZR, Y=ZF, C=0.D0, DIM1=NPOIN)
else
CALL OV('X=Y+C ', X=ZR, Y=ZF, C=-100.D0, DIM1=NPOIN)
endif

Option 2:
Add a variable named 'RIGID BED M '
to the geometry file with a value equal to the BOTTOM variable at the location of the breakwater and deeper than that elsewhere

Hi thank you for your suggestion to the two options of making submerged breakwater mesh.
I am really interested in the two options to make the submerged breakwater,but i still fail to make my mesh.
Is there any example or tutorial for the two options making the mesh?
Thanks a lot!
