What I do
- Source Code Verification: I verify that classes, methods, and properties used in
Enerflow.Workeractually exist in the local DWSIM source code (libs/dwsim_src). - Signature Checking: I ensure that the arguments passed to DWSIM methods match the function signatures found in the source.
- Deprecation Guard: I actively check for deprecated or void methods (e.g.,
CalculateFlowsheet2) and suggest the correct alternatives (e.g.,RequestCalculation).
When to use me
- Coding: IMMEDIATELY BEFORE writing any code that calls into
DWSIM.*namespaces. - Debugging: When a
MethodNotFoundExceptionorMissingMemberExceptionoccurs related to DWSIM. - Refactoring: When upgrading DWSIM versions or changing simulation logic.
How to Verify (The "Grep Check")
Since libs/dwsim_src contains the authoritative source code, use grep and read to validate your assumptions.
1. Find the Class Definition
Do not guess where a class is. Find it.
# Example: Finding the Flowsheet class
grep -r "class Flowsheet" libs/dwsim_src/DWSIM.FlowsheetBase2. Verify the Method Signature
Once you know the file, read it to check the method arguments.
# Example: Checking RequestCalculation arguments
grep -A 5 "public void RequestCalculation" libs/dwsim_src/path/to/Flowsheet.vb3. Check for Enum Values
DWSIM uses many Enums (e.g., PropertyPackageType). Verify the exact spelling.
grep -r "Enum PropertyPackageType" libs/dwsim_srcCommon DWSIM Pitfalls
1. Calculation Methods
- WRONG:
flowsheet.CalculateFlowsheet2(...)(Often void or deprecated in patched binaries) - CORRECT:
flowsheet.RequestCalculation(...)
2. Automation Mode
- Requirement:
DWSIM.GlobalSettings.Settings.AutomationMode = truemust be set. - Verification: Check
DWSIM.GlobalSettings/Settings.vbto confirm the property exists if you are unsure.
3. Thread Safety
- Constraint: DWSIM Automation is single-threaded.
- Verification: Ensure no
Task.Runwraps direct DWSIM calls without a lock, although the Worker architecture handles this viaConcurrentMessageLimit = 1.
