Function Documentation

CalculateDeltaTime()

double Kratos::ExplicitIntegrationUtilities::CalculateDeltaTime	(	ModelPart &	rModelPart,
		Parameters	ThisParameters = Parameters(R"({})")
	)

This method computes the necessry delta time to avoid numerical instabilities.

Parameters

rModelPart	The model of the problem to solve
ThisParameters	The configuration parameters

Returns

The critical delta time

InnerCalculateDeltaTime()

		const double	TimeStepPredictionLevel,
		const double	MaxDeltaTime,
		const double	SafetyFactor,
		const double	MassFactor
	)

This method computes the necessry delta time to avoid numerical instabilities (inner method)

Parameters

rModelPart	The model of the problem to solve
TimeStepPredictionLevel	The prediction level
MaxDeltaTime	The max delta time
SafetyFactor	The safety factor
MassFactor	The factor that multiplies the mass

Returns

The critical delta time
