FATAL: floating point exception (AMG divergence)

I'm running a two-way FSI transient analysis. I have pressure at an inlet defined by a UDF. When the magnitude is 70 kPa, the simulation runs swimmingly; but when I use 100 kPa, Workbench yells about a floating point exception and says 'a solver failure occured during the run in the Structural system'. The structural system, however, points to Fluent which reports
Divergence detected in AMG solver: temperature
Error at Node 0: floating point exception"
Is there any way to work around this? Why does increasing the pressure value only result in some temperature error?
Any advice would be appreciated,
