open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear all,

I try to runing the example cases named donau in the telemac2d, it is runing proprery. But when I start to change the number of time steps (for example, change the number of time steps from 900 to 9000), an error shows up.

I also check the boundary condition, it also no problem, since it is use the constant boundary condtion on inlet and out let.

Hello,

And what is this error. We never tried, but the flow must tend to a steady flow, so this is strange.

Hi




I also think it should be a steady flow because use the constant flow rate and elevation in inlet and outlet.

One more small qustion, Why when we set the flowrate by ourself. the flowrater unites are m2/s and not m3/s ??

Hello,

Never seen this error, it seems a problem in the steering file (when you change the number of time steps ?).

Where do you see that the flowrate is in m2/s ?

Dear JMH,

I changed the time steps in yesterday and the day before yesterday. I try it on both V6p3 and V6p2 version.

About the flowrate is in m2/s is the example made by myself. I set the inlet boundary condition and setting the flowrate and found that the flowrate is in m2/s.

Hello,

In fact it should be m3/s but it is not checked, it is just considered as a comment.
