Hi Marcelo (@marvasconcelos1) and welcome to SimScale!
We have plenty of resources you can use to get familiar with SimScale. Some of them are:
-
The documentation of SimScale
-
The “Get Started Tutorials”
-
Some random tutorials in general
-
Learning by doing with the SimScale Workshops
Or you can simply have a look at the Public Projects to see how others have set up their simulations and learn from them!
Let me know if you like the resources and feel free to give some feedback. Looking forward to see you create the first project with SimScale!! 
Cheers and happy SimScaling!
