JumpSystem equations must contain MassActionJumps, ConstantRateJumps, or VariableRateJumps #2098

Closed arnold-c closed 1 year ago

arnold-c commented 1 year ago

I am trying to run the example from the documentation and unfortunately running into the error JumpSystem equations must contain MassActionJumps, ConstantRateJumps, or VariableRateJumps. Code below:

using ModelingToolkit, DiffEqJump

@parameters β γ
@variables t S(t) I(t) R(t)
rate₁   = β*S*I
affect₁ = [S ~ S - 1, I ~ I + 1]
rate₂   = γ*I
affect₂ = [I ~ I - 1, R ~ R + 1]
j₁      = ConstantRateJump(rate₁,affect₁)
j₂      = ConstantRateJump(rate₂,affect₂)
j₃      = MassActionJump(2*β+γ, [R => 1], [S => 1, R => -1])
@named js      = JumpSystem([j₁,j₂,j₃], t, [S,I,R], [β,γ])

This is the line causing the error.

julia> @named js      = JumpSystem([j₁,j₂,j₃], t, [S,I,R], [β,γ])
ERROR: JumpSystem equations must contain MassActionJumps, ConstantRateJumps, or VariableRateJumps.

I tried this with both v 1.8.2 and 1.9.0-beta4, both within and outside of projects, and got the same error each time.

Any help would be appreciated.

Thanks

Don't use DiffEqJump, it doesn't really exist any more and has been replaced by JumpProcesses. Just modify your first line to

using ModelingToolkit, JumpProcesses

(It does look like the doc string needs to be updated to include using JumpProcesses.)

I'd strongly suggest you delete DiffEqJump from your environment to avoid issues in the future.

Thanks. That fixed it!
