Hi,

I want to run a case with AMI. Therefore I changed the MixerVesselAMI2D tutorial so that it uses my mesh which has also AMI patches. But I get the following error from the log.pimpleDyMFoam file:

Does anyone know where this problem comes from?

Well,

Looks my recent answer to you is irrelevant since you found out yourself. But did you resolve this issue? I have a similar problem (see http://www.cfd-online.com/Forums/ope...rformance.html)

I found the problem is related to viscosity. Do you have a solution? Relaxing U?

Regards,

Daniel
