(Solved) Error occurs executing AcuProbe.bat
Hi guys,
i am doing a CFD simulation using HyperMesh-AcuSolve.
When the solve is running, about step-40. the AcuTail display a message error as below:
acuSolve: *** ASSERTION in Function <lesGmres> File <lesGmres.c> Line <1379>
acuSolve: *** Error from fLesGetHbrgEig <10>
acuRun: *** ERROR: error occurred executing acuProbe'.bat
The model file is attached
please help me to fix it.
Thank in advandce!
P/s: when i change the eddy viscosity to a larger number, the solver ran completely at time-step 100.
but the result seems not right.

thank you, i solved my problems. it is because of the mesh quality.
Altair EmployeeHello,
i am also getting dame error which is mentioned above.
i am trying to decrease the mesh size but its big model so that i cant do it.
is there any other way to over come this error.

Hi Junta,
How you solve this problem? I'm facing the same problem.
Do you generate finer volume mesh?

hi alpharays,
well, i created a finer mesh by using 'zone mesh refiment'
however, each simulation is different, could you describe your case?
Because the error may come from many reasons, including the mesh size.
Please attach the two input (.inp) files - the first where you get the error, and the second where it runs but you don't like the solution - along with the two complete .Log files. It's quite likely the issues are caused by the very coarse mesh in the model. You probably need finer volume and surface mesh, thinner first boundary layer element (so more layers) and better resolution in the wake regions of the buildings.
Hi Acupro,
May I ask what “ASSERTION in Function <lesGmres> File <lesGmres.c>” refers to, like what are usually the parameters that result in such an error? And how do we go about resolving it.
I am also facing such an error. I understand changing the mesh size might solve the problem, but what exactly are those terms '' lesGmres'' etc..
Thanks in Advance

Could be mesh issues, boundary condition issues, problem definition issues, etc. Difficult to guess, as Junta mentioned...
