Hey again @MrPC,
I get what you mean. But I would say that especially SimScale is working keen on removing the barrier of being “difficult” by providing several options for new users to learn and understand simulation. Of course it is an iterative process but the longer you stay and work with the platform the bigger will be the outcome. 
Examples for projects you mentioned:
One of the biggest advantages you have @ SimScale is that engineers can help you with your project whenever you need it. If you get started “autodidactically”, please have a look at that page:
I will soon publish a dedicated page for every module of SimScale.
Stay tuned and enjoy your stay here. If you have any other problems with the forum/project et cetera, feel free to contact me privately.
Best,
Jousef
