An appropriate Mesher for creating sliding interface
 
Hi foamers,

I have a big problem for creating sliding interface for engine simulation.I created the mesh by using GAMBIT several times and unfortunately I couldn't succeed to run the case.I have an error :
Code:

Starting time loop

Courant Number mean: 0 max: 0 velocity magnitude: 0
deltaT = 5.55556e-05
Crank angle = 0.5 CA-deg
CG:  Solving for motionUx, Initial residual = 0, Final residual = 0, No Iterations 0
CG:  Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0
CG:  Solving for motionUz, Initial residual = 0.300902, Final residual = 0.000253697, No Iterations 57
CG:  Solving for motionUx, Initial residual = 0, Final residual = 0, No Iterations 0
CG:  Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0
CG:  Solving for motionUz, Initial residual = 0.000128037, Final residual = 1.20295e-07, No Iterations 66
Volume: new = 1.48807e-05 old = 1.48706e-05 change = 1.00444e-08
Motion continuity errors : sum local = 2.23621e-15, maximum = 3.88355e-14
Floating point exception (core dumped)

I know this error comes from setting the sliding interface and I think GAMBIT can't create a good mesh for using sliding interface!!!
Do you know any meshers that can create a good mesh for using sliding interface?

I appreciate your help.
Thanks and best regards,
Sasan.

GAMBIT mesh test on checkMesh
 
Can you run the checkMesh utility on your converted mesh? It might give some clues. What does it say?

thanks for your reply jose ,
checkMesh is Ok.
