Class DynamicRiskResult

java.lang.Object
neqsim.process.safety.risk.OperationalRiskResult
neqsim.process.safety.risk.dynamic.DynamicRiskResult
All Implemented Interfaces:
Serializable
public class DynamicRiskResult extends OperationalRiskResult implements Serializable
Result from dynamic risk simulation including transient effects.

Extends standard risk results with transient-specific metrics:
