Solving coupled ODEs error

Please login with a confirmed email address before reporting spam

Hello all,

I am solving a set of coupled ODE in a domain. The first ODE calculate displacements for the nodes in the mesh, and for each time step, the node coornidates are updated (large deformations).

Then I want to calculate strains again using other ODE, but I am getting the following error:

"The following dependent variables are not coupled
to all degrees of freedoms in the model: comp1.erz.
- Feature: Time-Dependent Solver 1 (sol1/t1)" (attached as picture)

I really do not understand why the solver complain about this one. Any help?

Thanks for your time,

Attached model.
