Calculate duration in MS Project 2016 based on custom 10 hour calendar

I am building a timeline. I have several tasks where the resources work 10 hour days 4 days a week. I built a custom calendar to reflect this. I have the approximate work hours needed to complete the tasks. I assigned the custom calendar to the resources and the tasks that are only done in 10 hour shifts/4 days a week. I entered the work hours and the number of  resources. It is calculating the duration for this work still based on 8 hour work days and a 5 day work week.
Is there any way to get it to calculate based on the 4 day work week and 10 hour work day?
I have Microsoft Project 2016.

Do you use task with fixedResource type? In this case task duration will calculate when you change your resources.
I create task, crete resource. In tab "project" I click "change work time", select MyResource, click tab "work week",  click "details",
click radio button "set days to these cpecific working time" and select working time for each day. (10 hours in 4 days)
and all is working!
