Is there anyway to unlock all three parameters?

[Brethern]

I accidentally pushed the lock button when changing the mass of the sun to equal that of a black hole.

Is there anyway to have all three unlock? I can't do any of my planned sims without having them unlocked.

Thanks.

The reason that one of the three values: mass, diameter, density is always locked is because one of the values (the locked value) is always dependent on the values of the other two:

From the diameter you can compute the volume so the functions are these:

mass = volume * density

or

density = mass / volume

or

volume = mass / density

Does that help?

[Brethern]

That actually does I was under the assumption that the values were independent.

Thanks for the reply.
