open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

In the Telemac2D model, SISYPHE was coupled to model sediment transport. However, at the first step SISYPHE couldn't proceed with the calculation because it detected NEGATIVE DEPTH PRESCRIBED ON BOUNDARY. But there is no negative depth on boundaries according to the printout. What could be the reason for this? Thanks!

Hi,

I think I've found the solution. I looked up the old posts and found it was caused by the inappropriate value of 'NON COHESIVE BED POROSITY'.

Hi qilong,

I'm currently experiencing the same problem you described above with 'NEGATIVE DEPTH PRESCRIBED ON BOUNDARY' when running telemac2d (vp6.1) coupled to Sisyphe.

I've defined and varied values of the 'NON COHESIVE BED POROSITY' in line with the theory but telemac2d still exits with the same statement.

Could you explain what 'appropriate' value of 'NON COHESIVE BED POROSITY' you used to solve the problem? And what proved to be an inappropriate value? Is the definition in the .dico file inaccurate?

Thanks!

Hello Steve,

At first I took the value from a previous model which was based on Telemac V5.2. The defination of NON COHESIVE BED POROSITY in the old version is different from the one used in the version 6.1.

In the old version, it has a keyword called COEFFICIENT FUNCTION OF THE POROSITY which is defined as XKV=1/(1-n). But in the new version, the keyworkd is called NON COHESIVE BED POROSITY which is the same as n.

In my case, I give NON COHESIVE BED POROSITY a value of 0.4, then I have no problems such as NEGATIVE DEPTH PRESCRIBED ON BOUNDARY.

Thanks for the prompt reply qilong!

'NON COHESIVE BED POROSITY' has a default of 0.4 in V6.1 so there must be some other problem with my model relating to Sisyphe. (I thought you might have extra information relating to the Parameter that I didn't have access to).

I'll keep investigating and re-post if I fail to solve the problem.

Cheers,
Steve
