Class ProcessValidator

java.lang.Object
neqsim.process.util.report.ProcessValidator
All Implemented Interfaces:
Serializable
public class ProcessValidator extends Object implements Serializable
Validates a process system for mass balance closure, energy balance closure, and operating limit violations.

Scans all equipment in a ProcessSystem and checks:

  • Mass balance closure around each equipment (inlet vs outlet mass flow)
  • Extreme temperatures or pressures that may indicate errors
  • Negative flow rates
  • Streams with zero flow
  • Overall process mass balance

Usage example: 


ProcessValidator validator = new ProcessValidator(process);
validator.setMassBalanceTolerance(0.001); // 0.1%
validator.validate();
boolean passed = validator.isValid();
List<ValidationIssue> issues = validator.getIssues();
String json = validator.toJson();

    • validate

      public void validate()
      Runs the validation checks.

    • checkStreamConditions

      private void checkStreamConditions()
      Checks all streams for extreme conditions.

    • checkStream

      private void checkStream(StreamInterface stream)
      Checks a single stream for issues.
      Parameters:
      stream - the stream to check
