open TELEMAC-MASCARET The mathematically superior suite of solvers

I am having a problem during a simple simulation. Can anyone help me with this?

Thanks :)

Hello,

Please first ban spaces in folders names.

Hello, I am still facing the same problem. What can be wrong?

Appologies, find attached the error after removing the spaces. it is the same error

Hello,

Can you run a TELEMAC-2D example, available in one of the $HOMETEL/examples/telemac2d subfolder?

With a few modifications in your steering file (as some keywords are missing or are mandatory, but not with the same error message as yours), I can run your example with my configuration.

Hello,

i can run every example from telemac2d folder. each example shows the message "my work is done". I am attaching one image as just an example.

I have tried again with the keywords, but the error persists, or maybe I am not using the correct keywords. Are there any guides on how to prepare the .cas files generally and also for some specific purposes? or what keywords are necessary for running the simulation.

Hello,

You only have 95 triangles in your mesh. Too few triangles to run in parallel (why did you choose PARALLEL PROCESSORS = 44?).
Please delete this line in your steering file.

Anyway, there are strange things in your geometry file + steering file:
- do you really want to mesh such a shape? Or did you intend to model a rectangle?
- you should refine your mesh, you only use triangles with 2 vertices belonging to a boundary. In particular to model open boundaries, 2 or 3 nodes are not enough. Have a look at the TELEMAC-2D validation manual to see examples of meshes,
- if the bottom elevation is positive (you have a constant elevation equal to 0.3 m), hard to prescribe a water elevation below this elevation (PRESCRIBED ELEVATIONS = 0.0;0.0),
- you will see that you have to choose a LAW OF BOTTOM FRICTION + a FRICTION COEFFICIENT.

I think you should carefully read the TELEMAC-2D user manual and TELEMAC-2D validation manual. You should also have a look at the TELEMAC-2D examples. Very helpful.

Hope this helps,
