[FAQ]

In problems when all domain interfaces have been set up using the automatic option, the CFX-Solver may give incorrect results when domain interfaces are close together. This can be especially true for thin solid domains, in which errors will be obtained in temperature values and energy balance. This is a limitation in the GGI intersection algorithm when all the domain interfaces are grouped into the same default interface because the separation distance between the interfaces is very small relative to the mesh size. A workaround for this issue is to use the expert parameter “ggi separation factor”.
