open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi, everyone

When I open the result file in Bk, it shows the WARNING:WARNING: 28916 bad values found in object DEPOSITION RATE. 28916 is the nodes number of my mesh. But I can look the result normally. What is the meanning of this warning?

Bestregards,

Hi Zqzuoqn,

This WARNING indicates the number of instances of "infinty" or "not a number" values found.
Each value scanned is checked with runtime library calls to the _isnan() and _finite() functions.

These values usually occur as a result of a "blow-up" in your simulation.

Cheers... Martin

Thank you, Martin

Can you tell me in where each value is checked with runtime library calls to the _isnan() and _finite() functions? And if I want to konw which value in some time is nan or infinty, how can I do that?

Thank you very much. Bestregards

Usually by looking at the object in wireframe style in a 3D view it's easy to spot where the problems are.

Thank you, Martin

But my value is 2D, and I have look at the object in wireframe style in a 2D view, but I cannot find the problem.

Thank you very much. Bestregards

You can view a 2D result in a 3D view.
