Hello, simulators

I'm trying to test co-simulation of XFlow 2020 and Abaqus 2017

I simply followed Dam-break tutorial given from XFlow2020 Tutorial Guide.

Once I enter abaqus commands given from the tutorial guide after running XFlow,

it goes well for seconds, and says "Successfully connected to host [my computer name] on port 1024.

I waited for hours, it never proceeds anymore.

Is it working well? I don't believe the tutorial example takes this long.

What should I do to resolve this problem?

Thank you
