Monitored Volume Time Step

An "AIRBAG1" time step is estimated into the Engine, but this time step will never control the time step during the run. If that is the case, it means there is a non-physical airbag definition in the input deck.

/DT/FVMBAG is only used for monitored volumes type /MONVOL/FVMBAG1. The Δ T sca and Δ T min can be defined to insure stability and a minimum time step size by triggering additional finite volume merges when the FVMBAG1 entity penalizes the computation. /DT/FVMBAG/1 is used to merge finite volumes when dt<Δ T min MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbwvMCKf MBHbqefqvATv2CG4uz3bIuV1wyUbqedmvETj2BSbqefm0B1jxALjhi ov2DaebbnrfifHhDYfgasaacH8akY=xipgYlh9vqqj=hEeei0xXdbb a9frFf0=yqFf0dbba91qpepeI8k8fiI+fsY=rqaqpepae9pg0Firpe pesP0xe9Fve9Fve9qapdbaGaaiGadiWaamaaceGaaqaacaqbaaGcba GaamizaiaadshacqGH8aapcqqHuoarcaWGubWaaSbaaSqaaiaac2ga caGGPbGaaiOBaaqabaaaaa@41F7@ .
