Only time derivatives involving grid time are allowed

Please login with a confirmed email address before reporting spam

When I use the ODE equation and the heat transfer module and the solid mechanics module, error reporting: only time derivatives involving grid time are allowed. After the solid mechanics module is removed, the error report disappears. What's the problem, please? Best wishes!!
