Good Morning Everybody,
when I was researching some information I found the package PDEInModelica which seems to have be not updated for the last 7 years.
Inside there is the package PDEDomains.mo, which with a few modification seems to work (at least on my OpenModelica) and allow the usage of a mathematical domain in OpenModelica.

However if the package has been left without the modification, there is most probably a reason. I tried to contact the last person who modified it, but I haven't succeed.

What Should i do? Perhaps if I upload the modified version here could be useful?
