DELT_dt_AddCond

(optional) defines a custom time step criterion

DELT_dt_AddCond($MATERIAL$) = RHS

If defined, MESHFREE will evaluate the given RightHandSideExpression at the start of each timestep and respect this value as an additional criterion for the maximum timestep size of the material with the specified tag. Good to know:

It is only possible to define DELT_dt_AddCond once per material, hence for incorporationg multiple conditions, these must be included into the RHS of the equation.
