Hello, Sir/Madam! I am currently exploring DWSIM version 6.2.9200.0. I am trying to make a material stream but the system always says that there is an error whenever I click "Accept Changes". It displays: DWSIM generated an unhandled error/exception.System.NullReferenceException: Object reference not set to an instance of an object. at DWSIM.Thermodynamics.MaterialStreamEditor.btnCompAcceptChanges_Click(Object sender, EventArgs e) in C:\Users\Daniel\source\repos\DanWBR\dwsim6\DWSIM.Thermodynamics\Editing Forms\Material Stream\MaterialStreamEditor.vb:line 740 at System.Windows.Forms.Control.OnClick(EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ButtonBase.WndProc(Message& m) at System.Windows.Forms.Button.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)For screenshot, please click the link:https://drive.google.com/file/d/1jg5j4WUbJOixP6di5alVFLtorjqOf6Dv/view?usp=sharing
What does mean input string was not in a correct format?
I am using version 6.1 update 3 of DWSIM on a Mac.The software does not accept the value of 1 for the vapour phase mole fraction. In fact, it does not accept any value.
Instead, I am getting the screen "Step 2 - Process Model details".Don't know how to choose Raoult's law. Can you please explain.
I am using v 5.8 u 11 of DWSIM. When I open the application, it does not open to the task manager and there is no option to select under the files tab to select a new steady-state simulation. What do I do?/
How wil i know what property package goes well with a compound is there any specific rule for the same or any standards of choosing?
I am unable to find "New Steady-state simulation" option under File Menu as displayed in the tutorial. I am using DWSIM Version 6.1 Update 1.
the status of the steam is always ''No Calculated''
in my dwsim installation the simulation settings are not as shown in the video am unable to find the thermodynamics tab?and also when i search for components i don't get components present in dwsim by i get components present in Chemsep
The "Apply" button is missing. Can you please help.
As there is no 'Appearance' tab with 'Name' field, how do one change the name of the Material Stream?
Cannot find the specification button for specification of the material. Can you please help.
This option is missing. Can you please help.
After dropping the Material stream into flowsheet from Object Palette, there is no automatic pop-up to enter the composition. So where do one specify the composition of the stream?
Thermodynamics tab is missing Under Simulation Settings. Can you please help.
It is said in the tutorial to add Benzene from DWSIM database, but current UI doesn't show any Benzene component from DWSIM database when searched for it.
This button is missing. Can you please help.
