Hello (word file would be better to read the quesiton)

I would like to see bolt force changes with regard to temperature and service load.

First, bolt is tightened.
Second, temperature is assigned.
Finally, service load is applied.

In order to run these simulations, I think I have two methods.
1) multiple studies
2) multiple steps.

(1) multiple studies
Study 1: Bolt pretension
Study 2: Heat transfer in solid-Thermal expansion
Study 3: Service load

Study 1 setting
1) Model configuration for study step
Bolt pretension : Enable
Heat transfer-thermal expansion : Disable
Service load : Disable
2)Values of dependent variables
Initial values of variables solved for : Physics controlled
Values of variables not solved for : Physics controlled
Study 2 setting
1) Model configuration for study step
Bolt pretension : Enable
Heat transfer in solid-Thermal expansion : Enable
Service load : Diable
2)Values of dependent variables Initail values of variables solved for : User controlled/Solution/Study 1
Values of variables not solved for : User controlled/Solution/Study 1
Study 3 setting
1) Model configuration for study step
Bolt pretension : Enable
Heat transfer in solid-Thermal expansion : Enable
Service load : Enable
2)Values of dependent variables
Initial values of variables solved for : User controlled/Solution/Study 2
Values of variables not solved for : User controlled/Solution/Study 2

Multiple steps
Step 1
1) Model configuration for study step
Bolt pretension : Enable
Heat transfer-thermal expansion : Disable
Service load : Disable
2)Values of dependent variables
Initial values of variables solved for : Physics controlled
Values of variables not solved for : Physics controlled
Step 2
1) Model configuration for study step
Bolt pretension : Enable
Heat transfer-thermal expansion : Enable
Service load : Disable
2)Values of dependent variables
Initial values of variables solved for : Physics controlled
Values of variables not solved for : Physics controlled
Step 3
1) Model configuration for study step
Bolt pretension : Enable
Heat transfer-thermal expansion : Enable
Service load : Disable
2)Values of dependent variables
Initial values of variables solved for : Physics controlled
Values of variables not solved for : Physics controlled
Question
1) Are the settings for multiple studies and multiple steps proper?
2) Would you please explain initial values of variables solved for/values of variables not solved for? using my simulation cases?
3) For steps, I can use stored values for values of dependent variables. when should I use them? if I just select physics controlled for both solved for and not solved for, does it run the simulation as I intended? ( For example, heat transfer simulation will be done, based on the values calculated from bolt pretension)
