open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear Users,

I hope somebody could help me with my nuber of vertical levels set up. I am doing simulations in a very big "tank" and I need a very fine mesh around the source- 1m. The dimensions of tank are 150x150m and hight is 500m. With Blue Kenue I set up the horizontal grid to 1m near the sourse and 2.5m everywhere. To see the turbulence effect I need to set up 1m vertical mesh as well, at least above the source water column. Since the height of the tank is 500m, so in order to achieve 1m vertical mesh I need to enter number of vertical levels as 500, but it does not work. The maximum number of vertical levels (that works) I can enter is 50 what is 10m vertical mesh. I am probly doing something wrong or it is limitations of my pc as I have not run it in parallel yet. Or maybe I need to modify the CALCOT subroutine. Please advise. I have attached my steering file. Thank you.

Kind Regards!

sorry the file was missing on my original post. Here it is now.

Kind Regards!

Hello Violeta,

The mesh on the vertical is not necessarily regular. Actually you can decide the position of planes, as soon as they do not intercross. See e.g. test case Rouse and file t3d_rouse.f where there is a refinement on the bottom (in subroutine condim), with an exponential function. You can have a size of 1 m on the bottom and much larger layers further up.

With best regards,

Hello Jean-Michel,

Thank you very much for your help, it is much appreciated. I will follow your advice.

Dear Jean-Michel,

Unfortunately I did not manage to sort my vertical mesh problem. Just as an experiment I used the same data as for Rouse case it was working up to the number of horizontal level as 50 but when I tried to increase it to 100 then it stoped with just message that Cas file failed to run. My ideal case would be to run for 500 horizontal levels as the depth of the "tank" with one open boundary is 500m and I would like to have all levels evenlly spaced with 1m elevation. I need this fine mesh in order to see the turbulence effect as I have a source at the bottom. I am not sure if it is just limitation of my PCs, as one I am working on is 32bit and another is laptop with 64. I have attached cas and f files if you do not mind to take a look. It might be some obvious mistake there that I cannot spot as I still have to learn a lot. Thank you in advance.

Kind Regards!

Funny, but I have problem with attaching files sometimes. I must be doing something wrong. I hope it works this time. Thanks.
