I am trying to simulate pressure acoustics inside a shell. The acceleration boundary condition is defined as

a_n = -(nx_smsh*u_tt_smsh+ny_smsh*v_tt_smsh+nz_smsh*w_tt_smsh)


When I try to solve the problem an error occurs:

Error: 6250
Failed to evaluate variable Jacobian
- Variable: nz_smsh
- Geometry: 1
- Dimension: 2
- Domains: {1,3,4,18}

What am I doing wrong?
