setFields -time <range> ?
 

Dear All,

by using "setFields -time 0,20 " is it possible to give a same constant temperature value to some cells at every time step during 20 seconds?

I tried but does not work.

pleased if you could give some idea how can I do that?

best regards

setFields will change fields that already exist, so all you could do with your command is apply the setFieldsDict commands to 0-20. If you want a source term during simulation, you'll have to either:

1. Program it into your solver
2. In 2.1.x, use the sources option
3. In 2.2.x, use fvOptions

thank you mutircios

i use OF2.1.1, buoyantBoussineqPimpleFoam solver.
By using sources option do you think i can determine a spherical volume inside the fluid region as a heat source?
regards

Yes indeed. I haven't used sources much so I'm not overly familiar with it, so you'll have to do some digging.

hi
I also want to use setFieldsABLDict to implement roughness in the channel, but the problem is that, by this command as a pre_processing it is just implemented for the first time step as an initial condition. but I want it to be the constant effect during the time. does anyone have idea about it?
