Hi foamers ,

Do you know anything about origin of Motion continuity errors ?
How can I overcome this problem?
I am simulating an engine with dynamic mesh and changing topology..
Code:
Starting time loop

Courant Number mean: 0 max: 0 velocity magnitude: 0
deltaT = 2.6455e-06
Crank angle = 0.0238095 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 = 0.213596, Final residual = 0.000179652, No Iterations 20
CG:  Solving for motionUx, Initial residual = 4.89248e-09, Final residual = 4.42683e-10, No Iterations 1
CG:  Solving for motionUy, Initial residual = 0, Final residual = 0, No Iterations 0
CG:  Solving for motionUz, Initial residual = 0.000100573, Final residual = 7.10585e-08, No Iterations 21
Volume: new = 48492.4 old = 48492.3 change = 0.0719435
Motion continuity errors : sum local = 1.22866e-15, maximum = 2.88108e-14
Floating point exception (core dumped)
Thanks and best regards,
Sasan.
