Compiling

• DWSIM can be compiled using Visual Studio 2017 or newer on Windows.
• To compile everything, change the Build target to 'Debug' or 'Release' and 'x64'.

dwsim5's Issues

Potential calculation erros in Double.TryParse and Double.Parse with Invariant culture and NumberStyles.Any

Issue (example):
Double.Parse("77,65", System.Globalization.NumberStyles.Any, System.Globalization.CultureInfo.InvariantCulture)

return 7765

Cause: System.Globalization.NumberStyles.AllowThousands
https://stackoverflow.com/questions/46109025/c-sharp-double-tryparse-with-invariantculture-returns-unexpected-result

Sample for fix:
use Public Shared NumberStyleAnyWithoutAllowThousands as NumberStyles = NumberStyles.Any - NumberStyles.AllowThousands

instead NumberStyles.Any

No mouse wheel present unhandled exception

When using DWSIM on a laptop computer without a mouse attached, if you scroll down, it gives an unhandled exception that mouse wheel is not present.
It is irritating and disturbs the flow of work.

Error on Application Load

Hello,
I am having this error when the program starts after compilation

An error occurred creating the form. See Exception.InnerException for details. The error is: The type initializer for 'CoolPropPINVOKE' threw an exception.

I am using windows 10

My compilation settings:

Thank You

Project did not build. Multiple errors.

Adding Refprop as property package

Hello,

Is there any way to integrate Refprop as property package in DWSIM?

Add multiple component lists?

When modeling systems that benefit from two different property packages (e.g. gas-fired boilers, etc.), it would be very convenient to be able to specify multiple component lists that each have an associated property package. For example, a "hydrocarbon/air" component list with methane, ethane, oxygen, nitrogen, etc. associated with the PR thermo package, and a "water" component list with pure water as its only compound associated with the steam tables package. This way, when constructing the flowsheet, I don't have to manually set every stream to the appropriate package.

I thought I'd submit this idea here before working on the code in case this was already in progress. Thank you so much for all of your hard work on this amazing open-source simulator!

Deleting a rigorous distillation column crashes DWSim

It is not possible to delete a rigorous distillation column from the worksheet without the application crashing.

Minimal steps to replicate:

1. Start DWsim
2. Cancel startup wizard
3. Drag rigorous distillation column onto flowsheet
4. Right click
5. Delete
6. Select "Yes"

Application crashes.

5.8.11 was working fine for a while before this happened. The same error is reported with 5.8.11.

I'm running lubuntu (Ubuntu 16.04.6 LTS, 4.15.0-96-generic).
The dependency versions installed are mono-complete: 6.6.0, gtk-sharp2: 2.12.45, libfontconfig1-dev: 2.11.94, libglu1-mesa-dev: 9.0.0-2.1, coinor-libipopt1v5: 3.11.9-2.1.

Edit: Summarising and clarifying the issue for future reference.

App crashes on startup (while trying to start from the CLI on Linux) if any of the recent files are corrupted.

I want to translate UI to Turkish. Could you point me to the correct files.

Thank you.

Need convert FormFlowsheet.Designer.vb to UTF8

Please convert file FormFlowsheet.Designer.vb to Unicode.

1. In FormFlowSheet.vb exists field PropriedadesDasSubstânciasToolStripMenuItem with No ASCII symbols
2. In FormFlowSheet.Designer.vb - PropriedadesDasSubstânciasToolStripMenuItem broken in other languages.

Question : basic unit tests for node graph UI?

I was really intrigued by the node graph UI built around SkiaSharp, etc. Is there a basic test application that one could more easily learn from as part of this project? It would be immensely useful to have a reference system available that others could build from.

Error when connecting rigorous distillation column reboiler duty
