srgb-error

This is just a warning. Somehow the Mantium logos are not inserted into the software correctly. The warning appears randomly on some systems. Attempts to fix it have all failed.
 
But as it is just a warning, you can ignore it.
 
Or did this affect anything else? You should be able to use MFlow, as you did before.

I am unable to run a simulation.  MFlow does not appear start a simulation as the scrolling text that appear in a separate pop up window does not happen.

Just to be clear. Can you build the case? Do folders like “system” and “constant” get created? Or does the “Run Case” button simply do nothing?

Yes, those files are created, but I usually have a DOS-like popup window open that shows the calculation iterations scroll passed as they are made.  This does not happen.

OK, so we have to figure out what exactly fails.
When hitting the “Run Case” button in MFlow, can you see if you computer is doing something, for example in the task manager?
If no, you could locate the *.bat file created in the case and try to execute that manually. If that works, somehow MFlow would not be able to run that anymore.

Folders named \’0\’, \’Constant\’, \’Postprocessing\’ and \’System\’ are created. Files called \’runFile.bat\’ (inside the \’input_files\’ folder), \’check_closed_stls.sh\’ and \’runCase.sh\’ are created. This is all, nothing else happens.

Ok, we need to find out why you cannot see that it runs anymore. I might simply be a problem of you not seeing it because all the scrolling text does not appear anymore. To figure this out, you have to check two things:

1. Open up your task manager and then in MantiunFlow hit “Run Case”. Keep an eye on the task manager and see if the system load increases.
2. Open a command window and manually execute the runFile.bat. This will pretty sure produce some text output. Please copy-paste it here.
