Error



Posted 14 years ago by Terry CORDONNIER engineer
Hi guys,

When i started simulation, an error message says me: ".....an error with elements 9532....look the supermesh...." and i can't do it again. "Start" button is off like all "simulation toolbar".
How can i restart simulation to watch again the exact error message.

For information in my "log panel" i read: "[b]ERROR:  0: FEM problem locked during running or paused simulation![/b]"

Regards,

Terry

Ok, it's a bug, i close my model and "simulation toolbar" is "on" even i run the model.
But i have a real problem. My error message is:

"[b]Non positive determinant for element = 9132. Obsviously, an extremly distorbed element geometry as a result of false mesh design and generation (e.g., negative areas). Check mesh for the indicated region![/b]"

But i don't find the indicated region on supermesh view !!??

Regards,

Terry

You are likely dewatering or flooding with extreme heads your model. If you run it in phreatic mode instead of free&moveable mode (aren't you ?), I bet you will see some crazy values.

Regarding the "start" button being freeze, you usually have to press the stop button before. Was that function frozen as well ?

Good luck !

Thank you Didier,

Indeed i run the model in "Phreatic" mode. But i think that my problem is something else.
Do you know how to find an element. Precisely, I am looking for the 9132 element, but i spend a long time with the "inspector" tool.

Regards,

Terry

A solution for the freezing simulation toolbar has been implemented in an earlier bugfix, can you check if you have the latest patch (current patch is p6 - May 25th 2011)?

A tool for searching a node number is not yet implemented. Workaround: Use the classic FEFLOW and reproduce the error message. Here, a red arrow will point at the corresponding node.

Thank you for your solution with classic Feflow.
It help me a lot. Quickliest than using a GIS.
