How to assign initial heads to a 3D model?

[flydream0428]

Can someone please tell me how to assign initial heads to a 3D transient model with TTIM?

Thank you for your question, @flydream0428.
TTim computes the head change caused by all the transient elements starting at time t=0.
The head change at t=0 equals zero.
You can add any initially steady state flow field by adding a TimML model.
TTim cannot simulate an initial condition that is not steady.
I hope this helps.

Just to clarify: You can add a TimML model to a TTim model using the timmlmodel keyword when creating a Model3D or ModelMaq.

Thanks a lot @mbakker7 , it works!
