Ok, thanks for your help!

Thanks for your reply.

The file is in the link below.

tank-basic.mo

I am a new user of OMEdit. I'm trying to simulate a simple tank with liquid discharge, but I have problems with the connections and ports.

How can I set the number/location of the ports of multiple devices (boundaries, tanks, sources, etc.) ?

How to set the fluid property package (example: liquid water) ? Modelica sometimes gives errors about "Redeclare Package Medium", or error about misconfuration of property package. This information is not clear to set in OpenModelica environment.

Thanks in advance.
